This is a really weird semantics argument. I view the updated ruleset as the same edition. It's much smaller of a change that any edition change from the past 20 years, so I really don't think it's a new edition. It would be "powercreep" compared to the 2014 content, which I don't think is necessarily a bad thing.Power creep applies books released within the same edition or half edition. So if they put out a book of good feats before 2024 which raises the power level for the current classes. A new edition or half-edition is NOT power creep, it's a new rules set. After 2024 power creep will come in new 5.5e books.
If they use the same basic ruleset with a few changes, its the same edition. If different versions of the same class can play at the same table without any major issues, the different rulesets are compatible, regardless of changes in the class's mechanics.
