The truth is though that it’s not an apple-specific thing. On the android side Asus was the last large phone maker to ship modern small phones, and even they have taken over their zenfone line (small phones line) with a large phone for the ZenFone 11.
Based on reports from companies, it sounds like the market is just not there, at least not big enough to warrant the R&D compared to “regular” phones which make them good money.
Thinner* since there are people actually wanting smaller phones (and I have a jack on my zenphone 10 so size isn’t an issue), they’ve been blaming thinness and water resistance for the drop of the jack
