I've always attributed that user-tradition as a Jobs byproduct; he was a unifying force for the user experience and that role hasn't been filled since his passing. There are lots of hands involved with many projects, but it feels there's no point-person or champion on this for many years.

From going back to dongle hell of the 90's via USB-C, to the conflicting marketization of the macOS products, the connectors proliferating on the iOS standards(now lightning and USB C!), the conflating of iOS apps into macOS space, dropping magsafe; it doesn't feel very user friendly when you start getting into the details.
