Authors are free to do as they please, but as an entitled member of the peanut gallery…aren’t there already enough small configuration languages? Seems like a distraction when there are already hundreds of schemes, Lua, Janet, etc.
I use kakoune, because I like the client/server architecture for managing multiple windows, which helix can't do. The less configuring I do the better, but I've hardly done any in the past year. It's nice to have the option.
I do use kakoune-lsp and kak-tree-sitter.
