Yeah, that's a documentation problem. It's never behaved that way. The
restrictions are enforced after startup files are read, which happens
after the environment is read. The restricted shell isn't actually all
that restricted, anyway.

Maybe you don't expect it, but it's always behaved that way, and there's
no reason it shouldn't.
