There might be some wording change to "upstreams allow" in the new
policy to include this as should-be-unbundled cases — although I'm not
sure it's valuable in the cases where the bundled libraries aren't

Possibly easy upfront, but then, what if there's an API mismatch
between either an update of this package and the system lib such that
the unbundled combination no longer works? Then, something that was
easy for the packager suddenly becomes a programming problem.

Find all the bundled libraries in all of Fedora, even with minor
variations in code and version. When there's a vulnerability,
automatically generate patches, bump the RPMs, rebuild test builds, run
them through automated testing (including a new test for whatever
just-revealed CVE), and ping the maintainers.
