The enter-to-rename behavior has been in Mac OS since near the beginning, when versions were just named something like "System N.M"). IIRC, I've heard they had very detailed UI design documents back then, that explained their choices (e.g. I've heard they explained the reason for the menu bar being at the top of the screen rather than the top of a window was the cursor will just stop there, requiring less mousing precision). So if that's the case, there should be documents confirming or denying your speculation.
