libc is confined by the standard. FreeType, on the other hand, can
deprecate, rename, and adopt interfaces much more freely. I failed to
grasp why a library like FreeType should have a record when a certain
symbol was adopted. It is not portable to keep multiple versions of
the same symbol. FreeType strives for extreme portability.

Here is a rather silly examples without actual versioning:
https://github.com/FFmpeg/FFmpeg/blob/master/libavdevice/libavdevice.v
and similar.
https://sourceforge.net/p/libpng/code/ci/libpng16/tree/scripts/vers.c
is a plain looking scaffold
