Still way more expensive than swapping a battery pack, and this mean leaving your phone to a stranger for a few hours or maybe a day if the shop is really busy. Anything that add friction to changing battery will help sell new phone.

I think last couple years' improvements to battery tech made software take over batteries as the bigger contributor to device obsolescence.
So this change, while welcome, is a bit late.
It keeps getting all updates and will keep for few more years.
Camera results massively improved cca 2 years ago with some update so that they are cca on same level as current ones. Plus I still has 10x physical zoom which trumps all current models, iphone pro max including since we still can't bypass physical limits of optics.
Really, 0 reasons to update and battery capacity is the only upcoming issue - still fine now but I feel the decrease a bit. If I could swap it easily myself without paying some phone shop to do it, that's a massive advantage.
