If I'm summarizing correctly, it sounds like there is no policy on 
exactly what to do here. I think removing the package would be pretty 
bad, because gmpy is designed to speed up numerical libraries, and the 
performance hit without it would make many libraries really painful to 
use. Given this, perhaps the dependencies should be Recommends instead 
of Suggests.

The guidelines I saw in the bugs filed on my packages (e.g. bug #937791) 
say to "document" the reverse dependency. Where do I document this?
