Why not just makes feeds template items so that a user theme can have an
 rss template for example rss.php, atom.php etc. and this is used
instead of the builtin feed handler.

If we standardise on hooks for the main places a plugin would want to
add and let the enduser extend some more if necessary.

This allows people to customise feeds to any degree without having to
muck around with object buffers and building/throwing away huge object
structures for every feed request.
