HEAD is still a waste of resources. the http body in the context of feeds is usually pretty small and does not consume a lot of resources compared to actually initiating (or even keeping) the TCP connection. HEAD also means the server as to do everything but send the data to make sure it does not need to sent it => waste.

Not at all. If you have the RSS as a static file - and that's the best way for a resource that is much more often read than written - the web server can just stat() the file and get the modified timestamp instead of having to open and read it.
