Even without this sort of stuff, too much worldbuilding can get in the way of player enjoyment in other ways.Not that I disagree with this in theory. People have fun in different ways. But it holds a danger.
I've twice now encountered GMs who were SO in love with their own world building that the PCs were an afterthought to them.
The First one let us encounter his world and move through it, but we were basically spectators who never did anything major. That was left to his own NPCs - who were the protagonists. To the point of when we were fighting the BBEG, we couldn't affect him but the protagonist NPCs swooped in and took care of it. I somehow lasted through the first time this happened. The second time this happened, I was out!
Years later, different city, completely different group. GM was a great storyteller, but it became VERY clear to me that the PCs were window dressing to the GMs world and where just there to "marvel" at the GMs world building without affecting much of anything.
My Monster of the Week game, for instance. I wanted to build a world without the "traditional" monsters (vampires, werewolves, zombies, etc.) and instead have different creatures--weirder ones that I had-made. Then one of my players, upon learning about the game said, "Can I play a werewolf." And... I didn't really want to let them, because it wasn't in my vision. I had them read a doc I'd written up on a different type of creature and asked them if it was interesting to them, which it wasn't. So I decided that I could make room for werewolves--and that player has recently said that their werewolf character is their favorite of all the characters they've made in recent years. This player wouldn't have been nearly as happy with that other creature, even if I thought they were cooler. (It also caused this setting to have a werewolf bowling team, so there's that.)
In other threads, people have talked about how there are too many races in D&D and not enough places to put them. With player input while worldbuilding, though, you can learn that nobody at the table wants to play an elf but someone really wants to play an owlin, so the DM can just not include elves, unless they have a good story idea in mind for them, and have owlin instead, and have the owlin take what would have been the elves' place on the map.
