I don't see any such uses, so that could work.

I agree - that the lib/vsprintf.c code seems to prefix
"%#p" numbers with "0x", as currently coded.

But I find borrowing the '#' flag for symbolic names
to be a slight stretch, as well as likely to confuse
some of us, such as myself, for whom these printf flags
are already a tad cryptic and error prone.

I'd be inclined instead to use "%P" for symbolic addrs.
