It's basically the same issue, but your fix
is too specific to your problem.

The easiest generic fix is to add a feature attribute
saying that the feature should only be propagated
to immediate dependants when it's used in usage
requirements.  It's probably necessary to mark
both <library> and <conditional> with this.
