I think he's saying just the opposite: namely, that maybe_lisp_pointer is a
mistake, in that it goes against the (solid) reasons we've replaced some calls
to live_string_p with calls to live_string_holding.

After looking into it I agree. I'll propose a patch shortly that does away with
maybe_lisp_pointer.
