Agreed, and this is the advantage of not caring about (and not installing) updates at all: I judge releases on two things: hardware merits and my own hardware’s suitability.
The latter only degrades if compatibility isn’t good enough (which takes years on end for me, especially on iPads), and the former now takes a lot longer.
I wanted to upgrade from my 9.7-inch iPad Pro to my Air 5 for these two reasons: the full-screen design of newer iPads, and the effect of apple forcing my 9.7-inch iPad Pro out of iOS 9 and into iOS 12, which significantly affected battery life.
Now? Now my Air 5 runs a perfect iOS version (iPadOS 15), and the full-screen design makes newer releases less appealing, so I should be fine.
Updates obliterate devices, so users who do update may find their devices unsuitable for use on grounds of insufficient hardware due to iOS updates’ obliteration... and I’ll never experience that.
