We didn't invent this paradigm; it just came from existing layout in
Fedora and is true of other libraries there as well. See for
example /lib64/libz.so.N vs /usr/lib64/libz.so. And note that the
symlink is owned by the -devel package rather than the base package, and
shouldn't be required for normal operation (and thus can live in /usr).
Of course nowadays they are proposing eliminating the distinction
between /foo and /usr/foo entirely (discussion at LPC).
