You make some good points.  I think what you are writing is that  
people don't *need* to keep using old versions of their revision  
control executable.  Such tools *could* be upgraded in a somewhat  
smooth pattern.

I don't necessarily disagree, but for various reasons, people don't  
seem to behave that way.

Maybe it is because they are afraid of encoutering new and  
interesting bugs in newer versions of the revision control  
executable, which in theory has the power to inject corrupt data into  
the shared, permanent repository and thus screw up everyone that you  
work with.  Actually that doesn't sound like a half-bad reason to be  
leary of upgrading.

Right, see this is a good example -- darcs isn't even included in the  
Ubuntu support plan, so it doesn't necessarily make sense to keep  
using darcs-1.0.9 just because it is the darcs that came with your  
Ubuntu Hardy.  Nonetheless, people appear to do so.

By the way, thanks a lot to Iain Lane for maintaining darcs PPA.  The  
existence of that PPA seems to make things a lot happier for Ubuntu  
users who are trying to upgrade to darcs-2.
