Actually, the feed protocol has been unofficially defined as feed:url, where
http is the default protocol for the url if none is specified. 
So feed:www.tbray.org/ongoing/ongoing.rss is really just the abbreviated
version of feed:http://www.tbray.org/ongoing/ongoing.rss .
https feeds would need to be fully specified as

I doubt anyone would use separate aggregators for rss 1, rss 2 and atom -
typically you'll have one aggregator to handle all formats.
I see your point though where handler: is more easily extendable - one
protocol to rule them all.

Initially this would be slightly more work as aggregator-writers would have
to register the handler: protocol with a dispatch-mechanism based on the
mime-type, and then also register the mime type to point to their
aggregator. If the handler protocol would be an official w3c approved
standard though, I can see future operating systems would come with the
dispatching mechanism built in
