zsh-devel +mp_completion variant thougts

Hello, I've just taken over zsh-devel port and one thing seems idiot to me: What if there is a macports update and that i want to update the autocompletion port command file? I'd have to do a new zsh-devel revision, and everybody would have to rebuild it just for this tiny update. So here's my proposal: Shouldn't we make a new "macports" category, with all of those files which do belong to other ports, but are macports specific? I think there are other ports like zsh out there which add files like that. So in the end, we would have zsh-devel without the mp_completion variant, and another port named macports/zsh-completion which would depend on path:${prefix}/bin/ zsh:zsh. Nice, isn't it? My two cents, N_Ox.
