Changing the default System account user name

[FoohonPie]

Is the setting safe? @Noah751’s comment here and an earlier topic both mention potential problems, though it isn’t clear if those problems actually still exist:

@niemeyer

The question is whether there is internal code that still refers to that user by id as indicated earlier in this thread, or if this is now fixed and it’s fine to rename that user.

I can see that I can do it, but I’m not confident that it’s safe to do so. Does anybody have any more recent info on this?

Thanks.
