That appears to be how Anaconda does things -- creates a conda package that
hols just the shared libs, then another one that holds the python packages
that use those libs. (I think there is a freetype one, for instance) It's a
nice way to let multiple packages share the same dynamic libs, while still
keeping them part of the packaging and dependency system.

But I don't see why you couldn't do the same thing with wheels...

(and I'm not sure there's a point if there is nothing else that uses the
same libs...)

you'd have to make up a "fake" python package -- but it wouldn't have to
have anything in it (Or not much...)
