You'd still need the signature to take that type though instead of a raw pointer

Right. What I'd love to see is a change that removes the footgun for everyone (which does imply deprecating as_ptr), but doing that in a way which interops with existing code taking *const char and resists misuse is important
Any solution which requires you to know about the footgun and actively do something to avoid it isn't any better than the current situation

That's true. I think replacing as_ptr with an &*const c_char method could be good but it does have some similar issues

Yeah that seems really easy to try doing a pointer cast instead of a dereference. Making &c_char created from a *c_char not UB seems most tractable to me
