I'd love to use this feature for updates of GHC. For every new version of GHC, libraries built with it are installed in a new directory and get a new ID, which means that I have to find and revbump every haskell port with such an update. Unfortunately ports are only re-indexed when their mtime changes, so while you could just set revision (or epoch, or some other variable) in a PortGroup, that would still not lead to those ports getting reindexed. We'd have to keep a map from PortGroup to Portfiles that use this PortGroup to modify portindex to correctly re-index ports when a PortGroup changes; note that this might also take quite long. I can imagine changing the GitHub PortGroup would lead to index update times of more than 10 minutes. :( -- Clemens
