I've cloned the repo now, and it seems indeed to be a backend like xterm
or nsterm etc.  It's called wrterm, and is implemented in ca. 8.5 kloc
of Rust.  I can't read Rust fluently, but I'd say It implements the
usual functions for such a backend and not more.

So, I agree, that's not very interesting in this context.
