I think it's worth the effort in order to help empower our users to make
changes to their grammars.  Otherwise we're back to grammars whose
source is legally-speaking Free but that most of ours users wouldn't
know how to change.

My guess is lack of motivation on one side (most editors using
Tree-sitter already provide built-in support to automatically install
relevant grammars, which is even simpler (but not empowering) for the
end users since they don't need administrators access to install the
relevant grammars).

On the other side is probably the difficulty of packaging Rust and JS
libraries which tend to be horribly misbehaved w.r.t what distributions
expect (with things like vendoring or dependencies on very specific
versions of libraries).
