> Ubuntu has a really persistent update mechaism built in.
The OP doesn't object to updates, but to unexpected breaking changes, where th change is caused by different design decisions rather than bugs. LTS releases should not have those.
No, I specifically object to updates, because in my experience you cannot separate one from the other. I don't want any updates that I don't have reason for... if there's new feature or better performance I don't care about them 99% of the time. If I care after research, I can install myself.
