I see, so in your opinion having a central engine won't be a bad
architecture design for Emacs despite major modes having their own engine.
I wonder: is possible for any other package to "take the wheel" from major
modes when it comes to indentation or a better approach would be offering
facilities for package authors and maintainers to outsource their
indentation to this central tree-sitter-based indentation engine?
I'm trying to picture how this would look like.
