Actually, all my patch does is to make avalilable an extra option on 
the PNG save dialog - a "save transparent pixel color values", which 
is true by default.

It is an extra do the PNG save that doesn't break any other thing, and 
give to the user control that would only be achievable by some 
maneuvers of making a selection based on the alpha channel, and 
zeroing the colors inside it, and which is useful, for instance, to 
make the file get better compression. 

If it is found to be THAT useful, it could be moved to the GIMP 
preferences, but either way, each file format's  save plugin would 
have to be changed to get aware of that. In any case this would be a 
Gimp 2.2 matter.  (And I think BUG 129472 could be merged in just 
now, in time to the first pre-2.0 without breaking anything)
