The comments on the article have some funny ideas about versioning.

Apple platforms manage to support the idea of a “deployment target” and binary compatibility; the new symbols are weak-linked. Broken old behavior is preserved with linked on-or-after checks.

Not sure what makes it so difficult for glibc.

You need quite a bit of coordination between your toolchain, your kernel, and the standard c library for that to work. Linux/GCC/Glibc has never had that.
