So I don't understand... cannot we just depen on libpng-dev (instead
of libpng12-dev) and upload and that's it?

Rebuilding "gratuitously" (just to introduce cosmetic changes) is not
nice, but libpng is a vastly/widely used package and if we make the
change it will save other devels from having to NMU our package to get
libpng into the archive, so I'm in favor of doing that.  Or am I
missing something?


Cheers.
