Again, I see your point, because I've been there :)
But you're missing an important point of view: do you rely on that data?
If it's a toy project, don't even bother, just ignore all my replies.
If you do rely on nextcloud and the data stored there, having a backup procedure and safeguards for the upgrade process helps a lot.
Next time you perform an upgrade you can proceed without fears and stress, and way faster (if you run on docker) and that frees up time to play with kubernetes clusters and webapp development :)
Except it's not your call to make, or OP's call to make.
You're already getting quite a piece of software for free, demanding extended long-term support isn't really fair, expecially if you consider that they offer a simple update procedure.
