How to draw the line between libraries deemed worthy enough to start a
soname cascade, and those that just don't matter?  We can make sure
that no other packages are affected, but still the change might break
home-brew software.  Do we care?

Yes, see yesterday's thread about the libpngs.  But as far as I can
tell, the library in question here doesn't use versioned symbols either.
It's just that libpng is much more widespread than libvorbisfile.
