I have tried a few latch type Arca Swiss clamps but found all of them less than satisfactory. Not necessarily from a safety point of view but from a users point of view. If it isn't real easy to use first then safety is only a secondary issue, to me anyway.
I have decided that there isn't a method which will provide 100% safety AND is easy to use. All the plates have problems to a greater or lesser point of view so I guess you run with the one that you feel the least uncomfortable with. In my case the Arca Swiss is my best compromise all round.
There is one that does work for me though and I have it on my camera only but not on all the rest of my tripods or heads or even my wifes camera.
Although a screw can come loose by itself there are usually only two main reasons why this happens -
1. tightened up carelessly in which case I consider this self inflicted or
2. the screw comes loose because of side pressure or a twisting action between the plate (or whatever) and the camera
Only the user can fix the first one but the second one can be fixed by using the pins that a lot of older tripods used to come with. This pin would screw into the plate and fit into a hole in the bottom of the camera so the plate cannot work the screw undone. If you look at some of the RC2 plates used by Manfrotto you will find a second small hole which was designed to accept a small plastic pin that could interface to the camera. Plus in my earlier days I saw a lot of these pins. Now I don't know if cameras have these holes anymore but the D800 does. So my bracket handle plate has a secondary small screw poking up into the correct place on the D800. The bracket then has a AS 70mm QR plate under it and the same screw holds them both onto the camera. The AS plate also has a locking screw into the bracket. So no twisting action can make anything come loose. The screw could come loose but I should get plenty of warning about that.
I pick the camera up and the feeling of security is just so great because I know that nothing will come loose by accident.

Most air crashes are due to pilot error. That does not make them OK.
Eveyrthing possible is done to reduce the possibility of pilot error,
and the severity of the consequences.
For example, in piston engine aircraft, the knob on a mixture control is a
different shape than the knob on the throttle. Good idea, no?
Sure, dropping and breaking a camera is not an aircrash.
But it sure can spoil your day.
Many once-common types of cameras in use today are no longer
made and so irreplacable. Parts also are no longer made, so much
be cannibalized from another identical camera, or fabricated in a
machine shop.
Also, some of these cameras (even some 35 mm--to say nothing of
large format) are much heavier then those made today. Some
(e.g., the Nikon F) really would stop a bullet (ask Don McCullin!).
Basically, the big Japanese camrea companies only make three
types of camera today:
* DLSRs (OVF)
* Digital, screen on the back (no OVF)
* Digital, screen inside (EFV)
Banished by the big makers are, the TLR, folding camera, box camera,
press camera, field camera, monorail camera, stereo camera, panaramic
camera. -- and anything that uses film (except Fuji's instant film cameras).
(Of course, some there are kludgey cut-and-paste ways to make
paramamas and click-move-click ways o make stereo photos.)
To cut assembly labor costs and stimulate customers to replaced all
their lenses, they'd like to discontinue DSLRs --- hence the heavy
promotion of "mirrorless".
Meanwhile, digital camera sales have declined by more than 70% since
2010, and are currently either flat or growing very slowly. Yet the
last Japaense maker to exit the camera business was Konica Minolta
in 2006 The same number of camera makers are vying for a much
smaller market.
This situation is maintainable only by keeping prices high while cutting
costs. And that won't play well during the next recession.
The future of cameras for photography--not counting cell phones -- is
uncertain. So dropping one can be a big loss.
