Even if there are technical limitations that prevent Apple from adding more I/O easily, as a consumer it feels like artificial segmentation/limitation.
Apart from the initial M1 MacBook Pro release, it feels like most products Apple has released in the last few years has always been missing one or two features, and the next release happens to have that feature. E.g. the first M1 Air did not have MagSafe even though the Pros did, and then Apple included MagSafe in M2 Air, but it didn't support multiple displays; now Apple is including multiple displays in M3 Air.
It feels awfully convenient that each generation conveniently has a nontrivial feature upgrade.... Apple has less incentive to make each generation "complete" -- by delaying features (more) consumers will feel obligated to upgrade per generation.
