Um, MANY cell phone repairs can be done with nothing more than a replacement part, the right screwdrivers, and a spudger. Add in a soldering iron and you can do even more. Admittedly, they're not repairs of the rework-station-needed type, but once you hit that point it's probably cheaper to just replace the damned phone.
It doesn't take all that much brain power to watch an ifixit teardown and replace a cracked screen/digitizer, or replace a battery.
As for "This will result in a bunch of idiots suing Apple, Samsung, HTC, etc. for a DECADE to try and force them to publish Service Manuals and provide "Spare Parts" for the (still unrepairable for most people, no matter what the law says) smartphones and other asininely-complicated embedded products, and to no real eventual outcome other than making some lawyers rich(er)." that will be Apple/Samsung/HTC etc's fault for not publishing the fucking manuals in the first place and instead trying to create monopolies on repair as well as planned obsolesence..
