Sure, but that's a very different situation.  If someone upgraded from 14.04.3
to 14.04.4, they definitely wouldn't expect it to break working code.  If it
did, it would be a pretty serious regression.  Upgrading to LTS maintenance
releases should be a no-brainer.

Upgrading from one LTS to a newer one, you *know* things are going to change,
so you'll review the release notes and do some very careful analysis of your
mission critical code.

Cheers,
