Surely. What's wanted is much the same as the proposed support for
indicating that ports don't build on particular platforms. (You want to
realise it isn't going to work before you install any dependencies.)

When the current warning was added, it was more of an afterthought, like
the default case of a switch statement that should theoretically cover
all possibilities. I don't think anybody expected that so many ports
would end up in this invalid state.
