> Vim/Neovim have already diverged.

They are still 99% the same. They still have the same mental model, shortcuts, commands...

> They have completely separate scripting languages now, config languages for the main config file, and Neovim has LSP support out of the box

I'm not saying there can't be work involved when moving from one to the other. But it depends on the user, their setup and is more akin to changing from one vim-version to another version, not like switching between two completely different editors.

From my experience, a (neo)vim-user will always be able to continue with (neo)vim or any other future flavor of them instantly on a high level out-of-the-box. Which is very different from switching to any other editor. I mean I have seen vim-users being challenged by nano, simply because it's so different from they established habits..
