Yeah, that's not the problem these changes are trying to solve.

As the referenced modules almost always provide part of the relevant API
(especially datatypes), I'm not sure this is correct. These requirements
aren't hidden behind the API, they're part of the API.

My understanding of Requires.private was that it was for hidden
implementation details (like the XML library used to parse fontconfig
configuration files) so that static linking would know to pull in the

But, I'm probably just not understanding the subtle difference between
Requires and Requires.private...
