EAPI extension to force rebuild of reverse dependencies
As you all know, it's somewhat annoying when a version bump in a
package such as xorg-server triggers a need to rebuild reverse
dependencies, and it would be really great if we could automate this.
We already have something that's very close to a solution in EAPI 3,
called the 'operator slot dependency' , but it doesn't quite fit.
It would be nice if we could tweak the spec to handle this case. If
you're interested in helping to flesh out this idea, please see my
comment about this on bug #192319:
