No argument on the stability. That part has been genuinely impressive and it is the sort of improvement you feel every day for a year rather than once in a demo.
But the maintenance release framing was the pre-WWDC rumour narrative, not what Apple actually shipped. The keynote was built around Siri AI. It has a dedicated app, a new Camera mode, an expanded Visual Intelligence, and Apple thought it significant enough to publish a newsroom post explaining why the EU won't be getting it. You don't issue a regional exclusion statement about a maintenance release.
That is really the point. If iOS 27 were purely refinement, there would be nothing for us to be excluded from. The exclusion list exists precisely because there is a headline feature. So in the US, iOS 27 is maintenance plus a new assistant. In Ireland it is maintenance. Same update, same hardware, same price, different product.
I'm not asking to be wowed. I'd just rather people didn't tell me the release was always meant to be modest, when the reason it is modest here is that the immodest bit was removed at the border.
