Why hasn't this been done before?

In the old old days crossing polarizers did not always work well for color photos.
I understand that there are now variable ND filters available but I have never tried one so I don't know if the color issue has been resolved.

I just ordered a new CPL from Breakthrough Photography (Their filters are not cheap but they're incredible). It's a mix of 3 stop ND and CPL my two most used filters. Why has this not been done before? Am I missing something. I know that I can stack filters but that is another issue altogether. Looking forward to getting this in my hands tomorrow.
Because Breakthrough's CEO, Graham Clark, is a filter fanatic. And the fact that Breakthrough filters are so thin means you can stack without vignetting.

This is nothing new. You just didn't know.
Other filtes, such as 85 color, have also
been combined with PL at least 40 years.

I can't imagine how that would work, which explains why I'm not an inventor.

Because most folks do not ever use an L bracket. I shoot in Florida wetlands and come across dozens of photographers every day. Only saw one L bracket all year.
It would just become an extra expense the camera companies would have to add to the cost of the camera, plus packing an extra accessory in the box. Plus, those of us who would never use one would be paying for those that do. No thanks.

"Why don't camera makers make a dedicated L bracket that comes with the camera when you buy it ??" Price perhaps?
Why not all lenses come with a lens hood?

I believe all if not most of Nikon, Canon, and Sony lenses come with lens hoods.

Just before I got to your post I was thinking the exact same thing. I love my Olympus lenses, but I hate spending $600 for one and then they want another $40 for a hood. (I bought the knock-off for $12)

Yup, as amfoto1 says, there are companies who have done it - I had the one from Singh-Ray in fact. The trick is they are more expensive and if you don't really need one or the other, than it's more cost effective to skip the combo.
The bigger issue is however, that the stacked filters are thicker and often vignette on wider lenses or the wider end of zoom lenses (I couldn't use the one I had on my 24-70 at 24mm~28mm).

SinghRay makes a CPL/Vari ND (1-10 stops).

The CPL + ND combos aren't the same as Variable ND.
A CPL + ND combo simply has a darker tint to it than a "standard" CPL.
Where a standard CPL may reduce light pass through by 1.25 to 2.5 stops (approx.), depending upon how strongly the polarizing effect is dialed in, a filter like the OP is using will have a range of light reduction approx. 4.25 to 5.25 stops, depending upon how strongly the polarizing effect is dialed in by the user. That's the effect of a standard CPL plus a 3-stop ND.
In comparison, Variable ND typically have a range of light reduction such as 2 to 8 stops or 1.5 to 9 stops, without polarizing effects.
Variable ND are notorious for their uneven effects and tendency to cause ugly, difficult to correct color tints. The more affordable ones (which aren't cheap), are the worst. But even the highest quality Variable ND (which are extremely expensive) aren't completely free from these problems. But, possibly more to the point, for still photography a Variable ND is rarely necessary. One or two fairly strong standard ND can more than sufficiently "shift" the exposure range for most still photographer's purposes.... such as a 3-stop and a 6-stop, which can be stacked to give 9 stops if needed (and if possible.... the vignetting Steve mentioned can be a problem with wide lenses). A Variable ND is probably more useful for video, where there is less range of exposure settings to work with and ND effects may be needed to "fine tune" exposure. Ideally, a videographer would also use standard (non-variable) NDs, too. But they may need a lot more variety of ND strengths and opt for a Variable ND to reduce cost and complexity.

Yea, I guess I just didn't know, thanks for enlightening me.

The've been around for more than sixty years and a lot of different filter makers have them in their program!

Dedicated to what? There are different clamps in use on tripods....Arca-Swiss, Manfrotto, number of others. One L-bracket doesn't fit all.
