Comment 3 for bug 1959757

This seems like a reasonable change, but I am worried about potential API incompatibility - etcd 3.2.26+dfsg-6 has been in 20.04 for 2 years now, so there'll be plenty of users, some of which will almost certainly have explored every possible strange edge case.

This is still a reasonable SRU - we don't want users to have to notice any incompatibility at the same time as they need to deploy a critical security fix. We should do some deliberate testing for API compatibility, though. What can be done there?
