On the original series McCoy was the chief doctor on the Enterprise. This business of overanalyzing and assigning the characters symbolic roles is something that fans came up with, possibly in fanzines during the original NBC run but more likely during the 1970s and that Roddenberry repeated back retrospectively. You don't find much of that stuff in things like, oh, the writers guidelines for the series.
QFT. Thank you. Thank you. Furthermore, as the movies went on and Kelley got older, Bones became less important in the so-called "triad" and the movies became the "Kirk and Spock Show".
Yeah, McCoy became the "this exposition is really boring, let's have Bones break in here with an acerbic aside" comic relief go-to for the writers.
