I agree with this. I have never been a vim/neovim/helix user, so there's little I can contribute here. But I have always used paredit commands as much as possible, in all languages, not just lisps, and that's still true now that I've switched to vscode from emacs. I'm curious whether any vim/helix editing operations are "tree-based" in a similar way to paredit, and also whether anyone's building a paredit-like editing system based on treesitter.
