Then using span's member functions would fail for e.g. a vector passed in.

I'm not concerned about the C++ generic programming experts who will know
to convert the incoming range to a span, but the non-expert who doesn't
know much about writing generics. Besides, what if you actually want a
std::span, not just "a span-like thing"?
