I proposed a generic way to handle this several years ago at WP.
This is tied in with my petition to have core handle the front end more because core would have the function for filtering the attributes that every theme would use.
I don’t think core should be doing the microformats or the schema. Let the plugins that know about the site’s data do it, but core can provide the functions.
But definitely, core should be fixed for hentry and hfeed.
