Use X-Debbugs-CC: when you file a new bug and Cc: it.

I can't see why renaming is necessary.  We have to
recompile anyway. When it is done, versioned dependency
and symbol versioning should work fine.

Suppose that foo is compiled with current libsdl-image1.2
(which uses libpng3) and libpng2.
1. old foo, old libsdl-image1.2 and old libpng2
  doesn't work, not supported, you need upgrade
2. old foo, old libsdl-image1.2 and new libpng2
  not supported, you need more upgrade, welcome to unstable
3. old foo, new libsdl-image1.2 and old libpng2
  this is what symbol versioning is for
4. old foo, new libsdl-image1.2 and new libpng3
  no problem because only libpng3 is used
5. new foo
  versioned dependency forces you to use new libraries

Better just encrypt it all in your head :-).
