Frankly, there's a simple solution. If you drop your weapon, you check it. Period. When the Rem triggers have slipped and fired upon release of the safety, which I agree can and does happen, it was because they took an impact, and guys didn't open the bolt and check the mechanism before they went back to "business as usual".
Messing around in my shop, I have been able to cause 700's to fail like this in the past, but again, all you have to do is open them up, which resets the trigger, and go about your way.
It wasn't 2yrs ago on this board that someone made a similar statement about the Savage Accutrigger being junk because it could fire with the safety on. He posted a video of a Savage, he pulls the trigger WITHOUT the accu-blade, and it clicked. However, he mistakenly assumed this meant the rifle would have fired, which it would NOT have done. The sear would be transfered to the accu-blade, so if the shooter weren't mindful, and pulled the blade, which would be MUCH heavier than usual, yes, it would go off without fully depressing the trigger itself, but again, if he dropped the rifle, and opened the bolt to perform a function test, unloaded, it would have rectified the problem.
Same deal with the Remingtons.
Frankly, any mechanical device can fail, especially if you have designed an experiment to target it's weakness. Ultimately, it's your job to keep your muzzle pointed in a safe direction, and your job to do a function test SAFELY following any event that might cause damage to your weapon.
If I'm brutally honest, I can name 3 times in my life that I've dropped a weapon. One My shoulder sling broke and it fell of my back. The 2nd, I fell down a creekbank when a ledge gave way, and the 3rd, my revolver fell out of my holster that had came unsnapped while I was climbing into my deerstand. Taking the time to do 3 function tests SAFELY over the last 20yrs is nothing.
