This feels like a big piece of work to be pushing in right before a release.

It worries me because now there's an invisible piece of metadata floating
around that neither OS packagers nor library maintainers can see. In a way,
this feels strictly worse than having a package just plain break, because
it's not hard to imagine a cycle of "package breaks; magic invisible
dependency update silently fixes it; new version is released; package
re-breaks because maintainer never found out about previous breakage".

I could be convinced that in fact everything is going to be awesome and it
will all somehow work, but in the short term I'd prefer to delay sprinkling
invisible dependency pixie dust on packages, and let this wait until the
next release, 3 months down the line.
