(as well as generally making any assumption that the compilation and
runtime environments are and remain related - through the life time of
the binary, in all of its lives on multiple computers)

A different thing would be compilation of the C library on demand
(say with something like tcc) and discarding at reboot.

In comparison, compilation in advance and reuse seem to be much more
efficient and manageable. That's why we have got a pretty stable kernel
ABI, after all. (The same goes about a stable libc ABI versus the
applications which musl also does right, thanks Rich)
