Coping with the delicacies introducing further challanges users, which 
might be even more difficult than this medium sized incompatibility.

The difference of a fully integrated release bundle and "a development 
snapshot" is increasing more and more -- since the bundles are getting so 
advanced.  I would not like to see the clear distinction between 
production quality releases and arbitrary snapshots diluted.  Some users 
might even think that a snapshot is always the latest and greatest thing, 
while in reality it ages much faster than proper releases.
