Dude, not having root is objectively safer, and grapheneOS is security first.
If you want a rom that gives you absolute freedom, there are those as well, but it’s not as secure.
P.S you can root grapheneOS, it’s just not recommended or catered to and while I don’t agree with their tone and the obfuscation of it, I don’t think it matters as it just completely goes against security.
