Great, I've pushed this now.

Yeah, I'm uncertain. For long running systems, it's probably good to
update the packages, without having to adjust the service configuration
for changes like this. If there was a "stable" channel to track, which
didn't include updates to services, but did include important package
updates, then that may be useful.

Also, just making the errors relating to service configuration may be
more impactful than adding extra deprecation support.

Thanks,

Chris
