When taking a development snapshot users will get the full load of 
accidental incompatibilities, not just the 'a set thing, and usually get 
into a pitch somewhere in the middle of two official releases.

The situation is different for test releases, because they are *almost* 
the next release, so any efforts to port towards them are not lost.
