If I can express my opinion, I agree with Clemens.

In my opinion binary only ports should be allowed only for a very
restricted subset, where the effort is justified by the extreme complexity
of the build (and I'm also I'm not sure about that even, if someone managed
to build it, we should be able too ☺) or the port bering binary only (e.g.
