"profile" was a fine idea, but I think the opportunity to use it to
affect the scope of class (or rel or ...) values has long passed.  Far
too much software has been deployed which interprets these names
without any knowledge of "profile" scoping (e.g. CSS selectors).

If you really want these names grounded in URI space, I think the only
way forward is to bypass these legacy issues by starting from scratch
with new attributes.
