I find it pretty simple. Being a sword-swinger and being a spell-caster is ultimately a matter of aesthetic. Having simple gameplay with relatively few choices and widgets, or more complex gameplay with more choices and widgets, is ultimately a matter of playstyle preference.
You should be able to combine your preference of aesthetic and your preference of playstyle in as many possible permutations as possible. If there are simple sword-swingers, there should also be complex sword-swingers. If there are complex spellcasters, there should also be simple spellcasters.
There's a divide: people who think like you (and I) that play style and aesthetics should be dissociated, while others who think that, since D&D has always wedded them together, they should remain so.
For me, D&D is a dungeon-crawling system where magic is necessary for survival which might be why I don't quite understand the divide.
And here we see another divide: One where people think D&D should remain a game where you HAVE to have a spell caster (try playing the Curse of Stradh Adventure League campaign when no caster shows up... it was NOT designed for that AT ALL and it's BS) in your party to succeed, and those who think it should be possible to succeed without a caster. Not even an Eldrich Knight or a Monk.
