Neovim provided Bram competition, but he has not copied those features from Neovim.

vimscript9 doesn’t look or act like Lua (it still acts like a first-class citizen, unlike Lua) even though it is definitely improved over the previous version.

There have been terminal scripts for a while, but adding virtual terminal support was something resisted because a lot of people ran vim in a tty or with tmux. (Strictly speaking, terminal support is only something that to me makes sense for gvim and the like, otherwise you’re getting into terminal emulators all the way down. So much for the neovim philosophy of ripping unnecessary things out.)

And async was the entire reason that Neovim hard forked from Vim. Bram did not like the patches and asked for changes. The Neovim developers didn’t like the changes, so they hard forked. Bram implemented the async features / API surface that he wanted shortly thereafter.

There is a constant push from the Neovim camp that Vim is stagnant, backwards, dead, etc. None of this is true, and the messaging should absolutely stop. Frankly, I’d be happier if they rebranded from Neovim, because IMO they’re not vim and have stopped caring about compatibility with vim.
