"Always"? 2019 wasn't _that_ long ago that everyone's forgotten it
existed already, is it?
https://musl.libc.org/time64.html
https://git.musl-libc.org/cgit/musl/commit/?id=38143339646a4ccce8afe298c34467767c899f51

For musl's time64 transition, the impacted non-libc libraries which
used time_t in their ABIs just took the ABI break. Distros rebuilt
everything that needed to be rebuilt.

Taking an ABI break is also what 99% of libraries are doing with the
glibc transition -- I suppose with libselinux being the exceptional
case.
