The biggest reason to rev bump is that if you don't, the archives are 
useless. They get downloaded and installed, then rev-upgrade immediately 
detects that the linking is broken and rebuilds from source.

If the original question was about whether the rev bumping should be 
automated, well, maybe. We could certainly run rev-upgrade in report 
mode on all a port's dependents after it is updated. Do we then want the 
system automatically committing a rev bump? I'm not so sure. It might be 
better to just email a warning to the maintainers.

A concept of an archive revision as distinct from a port revision might 
be useful here.
