First GrapheneOS (and maybe e/OS? Not sure as I haven't looked at them) is a fully featured OS and not a ROM. Second, it depends on the level of attestation, but GrapheneOS only passes MEETS_BASIC_INTEGRITY (again, not sure on e/OS).
And Google already "changed something drastically" as SafetyNet is deprecated (replaced by PlayIntegrity).
My apologies, I have no idea of the difference between a ROM and a mobile OS, since I use both interchangeably (colloquially speaking). Is this a GNU/Linux like affair?
I didn't know about play integrity. Is this new with Android 14? I'd be OK with not caring but most mobiles in the US don't have custom ROM support any more. I'm waiting for KernelSU and custom patch support to grow so as to modify my mobile at all. I do not like where the industry is going. Even the FP5 was not released here (absolute shame)

Most people mistakenly do. GrapheneOS much prefers people to use the proper term of OS, so I try and do so.

Nope. PlayIntegrity was announced anout 2.5 years ago. SafetyNet actually sunsets 31 Jan 24, unless the dev got an approved extension, and then it's 31 Jan 25 for that specific app.
