If all you've changed is the default variants, then increasing the revision to force a rebuild would do nothing other than waste everybody's time, since everybody who already has the port installed would keep their existing variant selections on upgrade—unless you've removed one or more of those variants. If you have, for example, removed the gcc46 variant and added a gcc49 variant, or removed the clang33 variant and added a clang34 variant, then increasing the revision would be proper to ensure everyone has the port installed with variants that currently exist.
