The purpose of namespace.h (which is internal to libc) is so that
calls from libc to things that are supposed to be libc functions, but
are nonstandard, aren't disrupted when programs provide their own
symbols with the same names. If there aren't internal uses in libc,
namespace.h has no effect.

namespace.h would not help in this event; this would require bumping
the major version of libc.so, which as you may have gathered is a
"nearly never" event.

now that the functions are in libc, they're in libc for keeps...
