VSC has tons of customizations available, perhaps even beating Vim in the number of exposed configurations. The problem with Vim configurations is that a lot of them feel obvious, and the ergonomics of dealing with configs is painful and frequently calls you to reference outside material.
I'm not sure I'd say that it beats vim/neovim, but I agree with your point about ergonomics. I would say the vim manual is a fantastic resource, I've never felt the need to reference outside material.
Neovim has already integrated many of the "obvious defaults" (see :help nvim-defaults), but if you're a user and feel that something is missed you should file an issue.
I personally don't mind that the defaults may not be what I'd like, as once they are set, I spend very little time modifying my system configuration. I realize this can be a barrier to new users though.
