As discussed

tactically, if we change the role_allows to use x_node it would eliminate the params code, and it should just work...long term, there's gotta be a better way that avoids override role_allows at all, and passing in the correct feature from the caller

role_allows shouldn't be dynamically be building features though - something else should be doing that - I'm not sure how the toolbar code is working though
what I think has to happen long term, is we shouldn't be using basic buttons, but should have custom subclasses of the button for tenant stuff
