Refresh my memory:  under what circumstances, when binary compatibility has 
been broken, would changing the package name *not* be a good idea?

Can we come to a consensus that we don't want to spend our (in many cases, 
limited) Commons development time re-hashing the same discussions over and over 
again, wherein we try to avoid the package rename and related tasks, only to 
conclude in the end, that yet again we need to do the rename after all?  That 
is all James is trying to accomplish by bringing this to a vote.  If this 
process allows us to establish a general rule, and its effects turn out to be 
overkill 0-50% of the time, yet cause no actual harm, then this measure will 
still be an undeniable success.
