In a word, No.

I agree. I wish when digital sensor development started, two things happened. One, the cost of making a digital sensor was much less than it was. Two, the manufacturers had faith in the fact that the product would be a hit with consumers.
That would have led to FX format sensors from the start and all this falderal regarding crop factors would have been non-existent.

The crop factor is a simple thing and for those who understand it don't really need it. For years people used cameras of different formats and they didn't need to call something cropped or using crop factor. The crop factor was intended to help simplify the lens selection but it has been proven to be the source of endless confusion for many.

You have to be very careful changing cropping modes. When the focal distance of the lens changes, the dimensions of the camera have to change with it. If you set your cropping mode too small, you will need tweezers to make any more adjustments in your settings. [ /S]

Crops out west are having a tough time with the excessive heat.

Yes! That has been my complaint from the beginning. What a mess! Also, "mm" should be used to refer to all sensors. When I see "4/3," or "1/1.23," my mind fuzzes over. Of course, we could use "Normal" for 35mm, "Smaller" for crop, "Even Smaller" for 4.3, etc.

I guess we should reserve the term "crop" for our food supplies.

There is no difference in distance between the end of the lens and the sensor for either full frame or crop sensor cameras with the same lens mount. The sensor doesn’t move. Crop mode just uses less of the sensor.

It’s changes the angle of view which is also a part of the focal length. I think that’s about all.

Focal length is focal length. Lens angle of view is the lens angle of view.
How much of the angle of view that is used (what the sensor sees) is different,
therefore yielding a perception of a change in the angle of view and focal length.
The "lens's" angle of view does not change, same with focal length.

A lens has its focal length. It also has the angle of coverage which is the widest angle the lens can be used for by using a large sensor. Pass that point you don't get any wider angle of view just vignetting. The angle of coverage and the focal length of the lens determine the size of the image circle. The angle of view does change with sensor size providing the angle of view is equal or smaller than the angle of coverage.

"effectively" on the sensor.

If the FF and the crop sensor camera use the same lens mount then the distance is the same for both. Camera with smaller sensor and has its own lens line do tend to have the lens closer to the sensor than those with larger sensor however this is not always so. For example the Nikon FF Z mount camera has its lens very close to the sensor.
