I still think writing a lisp interface to dlopen and dlclose would iron
out a lot of things in the details and make it useful for treesitter
related stuff.  Or is the locking down the ffi interface done for FSF
reasons?

On another note, I also went through the same process with yaml-ts-mode,
A pointer to where the treesitter plugin is available is missing from
the docs.  Then one has to turn to third parties for this information
and to find the providers and toolchain providers and do the dance to
their tunes.

But most disappointing thing was that the modes come with absolutely no
navigation functions. These are structured files, and emacs has provides
way to navigate the structures.  This is a general quality defect from
to "prog" abstractions.  (when the facililties are provided they are
inadequate and a dedicated mode would have taken the diligence to do it
right)
