Put another way, so name bumps are for when incompatibly changing the
API, but these functions were never officially part of the API.  Any
program that used them, was using the library in an off-label way, and
they can expect undefined behavior from doing so (including undefined
symbols errors at startup).

Likely, there are no such programs anyway, so it's moot, I guess.  I
guess there's a slight risk a program isn't using lazy binding, but
not sure it's a big enough risk to bother caring.
