No. It means that they understand that there is a not insignificant number of people out there who play the game to relax and not have to worry about managing a bunch of resources.
You can't unring the bell. If the core fighter were more complex, those players would be screwed. If you make a simple fighter and have a more complex subclass addon, both those who want a simple fighter and those who want a more complex fighter can be happy.
I think there are "genres" to complexity.
The kind of complexity that we often imagine when talking about, well, complexity is the book-keepy annoying kind of one. Many people don't like it — I'm among them.
If anything, my proposal can be a simplification — now, "I don't want to read the rules, give me a simple class" kind of people can skip on reading or thinking about different weapon types.
"Uhhhh is a longsword better than a shortsword? What should I pick? What? Feats? Girlie I'm just here to smack people with a stick, give me something simple!" (pretty much a verbatim thing I've said myself) is excised entirely: you only read one weapon at a time. You don't have a million options, you only have one, maybe two.
You inflict a critical hit so strong your sword itself snaps from the impact! You grab another weapon and it's.... [roll on a weapon table] a spear! GM hands you a piece of paper that says:
Spear
Damage: 1d6 Piercing
Immediately after you take the Attack action and attack with this weapon, you can use a Bonus Action to make a melee attack with the opposite end of the weapon. The weapon deals Bludgeoning damage, and the weapon's damage die for this attack is a d4.
And stay back!: While you're holding a spear, you can take a Reaction to make one melee attack against a creature that enters the reach you have with that weapon.
And you get to do something new without being overloaded with complexity. You get to protect people for a while, then deliver another crit (and break your spear), roll, say, a pile of daggers (and, idk, get to do a lot of attacks? one attack, one attack from Nick property, bonus action attack for two-weapon fighting? Something like that?)
So a "smack people with a stick" player gets to play around with different (yet still simple) playstyles without delving deep into the rules and reading different feats and whatnot.
