The idea was probably that you really only need to publish a "future" article if someone is actually looking at the list of articles - and so you only need to update the feed when that happens.

Not sure if that makes sense any more. However, moving the call to lib-common.php would obviously put even more load on the server since the check would then be run for every call to Geeklog, no matter what the current user is doing.

I think the type was really only used to figure out if we need to update all the feeds or only the feeds of a specific plugin (see the check in COM_rdfUpToDateCheck)

Is that not what it's doing now? When you edit, say, a calendar entry (as an admin), COM_rdfUpToDateCheck('calendar') is called and only the calendar feeds are updated. That the 'calendar' bit is passed down to the plugin is really just redundant information, I think.
