RDF module conflicts with overridden taxonomy_term_page() implementations

I have determined that the "taxonomy_term_feed" which is being adding as the first parameter is coming from the RDF module. This problem affects any module that overrides the taxonomy_term_page() callback, such as Taxonomy Manager or i18ntaxonomy.

Currently, I am hacking around the problem by adding an extra parameter to the callbacks in 18ntaxonomy & Taxonomy Manager. However, this is not a very sustainable solution. It would be better to fix the problem in the RDF module so that the first parameter being received by the callbacks is not taxonomy_term_page. I suspect that the problem is in the rdf_feed_callback handler, where it is returning to the Drupal menu handler. For some reason, this works OK with the default taxonomy_term_page() callback, but with the other ones, it has "taxonomy_term_feed" as the first parameter and the term id as the second.

Actually, after looking in the {menu_router} table, I believe that the issue is with line 117 of the rdf.module: $items[$path]['page arguments'] = $arguments;. It is adding the "taxonomy_term_feed" as an argument but the alternative taxonomy_term_feed() implementations don't have a parameter to accommodate that.

EDIT (7/8): should have said "the alternative taxonomy_term_page() implementations"

This issue, I've determined, also means that I can't use the RDF module (or anything that depends upon it) with Panels 3, since the Delegator won't override taxonomy/term/% as long as rdf_feed_callback() says it's handling it.

I am not sure where to go with this issue at this point, since it seems like this is a broader issue than just with RDF module. Overall, there should be a way for menu_callbacks to partially override the default implementation, so that they don't conflict with each other but I have no idea how to accomplish that.
