Rack rails on network equipment

I’ve seen Dell rack equipment leap for safety (ultimately very very unsuccessfully…) in big earthquakes.  Lots of rack screws for me.

We selected Dell switches in part due to Dell using "quick rails'' (sometimes known as speed rails or toolless rails).  This is where both the switch side rail and the rack side rail just snap in, thus not requiring a screwdriver and hands of the size no bigger than a hamster paw to hold those stupid proprietary screws (lookin at your, cisco) to attach those rails.

Stock rails didn't work at all for us unless we used wider racks, which then, in turn, reduced floor capacity.

Am I overthinking this and artificially limiting myself by excluding vendors who don't ship with toolless rails (which is all of them now except Dell)?
