That's the main problem with most of the neovim GUIs—they get opinionated about what a Vim GUI should be. First, foremost, and always, it must be vim in a GUI window. Second, it must have native OS keybindings and integration (clipboard, menu, etc.). Finally, it should be able to have possible extensions that work well with existing plug-ins. (I use Fern for my file tree. I don’t need a built-in file tree that is always visible.) They must, at the core, always be vim. This is why I think that Oni2 was a mistake and why it’s one of the few software packages I regret paying. I don’t want vim motion keys with VSCode extensions. I want a Vim GUI.
Thanks for pointing this out. One thing I like is being able to command tab in MacOS -- if you have multiple terminal windows it breaks that, so any kind of GUI wrapper, even if it's basically just a glorified replication of the terminal app, is useful from a usability perspective. (To me at least)
That's how I originally moved from vim to MacVim -- I wanted terminal for sysadmin stuff, something like Sublime for coding, TexMaker for LaTeX (because it's it's own beast), and so on and so forth.
