Moreover, as you said, it is included in the good old policy, which is
even a quizz question iirc:

1.	You change a package's ebuild to install an init script.
	Previously, the package had no init script at all.
	Is a revision bump necessary? Why? What about when adding a
	patch?



For virtuals, they are simply packages that install only VDB entries, so
the above applies too.
For eclasses, I think we all agree that it is better to store them in
VDB too (otherwise we can't remove them, ever), so again the above
applies.
