I wouldn't object to another stand-alone maintenance program, which I 
could choose to run before dirvish-expire, which would attempt to 
determine if some backups were more valuable than before and change 
their expiry date to well in the future.  It could be triggered by 
finding runs of failed backups, backups where more than a normal 
percentage of the files have changed, etc., etc.

The biggest problem I see is translating the "just do what I mean" 
heuristics into algorithms that a significant percentage of dirvish 
users can agree on.  ;-)
