Doesn't that invalidate safety net?
Sorry I'm not 100% sure what your asking. If you're asking about custom roms, I'd trust many custom roms (Graphene is my favorite) better than a lot of manufacturers's roms. And a bootloader that can be re-locked is a big boost to security, since it requires that the OS be signed by the devs instead of making it easier for malicious code to be shimmed in and run at the OS level even if I install a custom operating system.
SafetyNet is the name of Google's tamper protection thingy. Basically, if it's not a trusted chain, safety net won't pass.
This doesn't impact phone functionality, but some apps check for this and refuse to work if it's not passing. Google Pay is one of the more well-known examples. Some other banking apps will also check for it. Oddly enough, Pokemon Go also used to (not sure if it still does).
Ah, sorry, yeah potentially. I've heard that banking apps won't work most of the time (but usually just use the web any way so can't confirm). Though oddly if you wanted to use Google Play on Grapheme it works perfectly fine, so maybe not.
