One general technique I like is the "warn and sleep" approach; example:
https://github.com/coreos/rpm-ostree/pull/2098

Of course, printing to e.g. stderr or even more strongly adding a sleep(5) call in the middle of cryptographic libraries has a huge blast radius on its own.  But it's smaller than removing it entirely.  

(And, remember I am a big fan of the mental model of rolling out changes to the OS core first, not all packages, so some sort of opt-in warn-and-sleep approach could even be prototyped out in e.g. Fedora CoreOS first, where we have CI that covers most things we care about)
