What does it take for this to never happen again? No operator should need to plan and execute an upgrade for a whole year to upgrade one year's worth of code development.
We don't need new policies, new teams, more releases, fewer releases, or anything like that. The goal is NOT "let's have an LTS release". The goal should be "How do we make sure Mattieu and everyone else in the world can actually deploy and use the software we are writing?"
Can we drop the entire LTS discussion for now and focus on "make upgrades take less than a year" instead? After we solve that, let's come back around to LTS versions, if needed. I know there's already some work around that. Let's focus there and not be distracted about the best bureaucracy for not deleting two-year-old branches.
