True, I don't know why I didn't thought of it :-).

No rush, it's not like this was something people complain about, and I
have seen all the tree-sitter work going on.

Have you seen the other patch, where flags are sanitized, that would

not undrstand. Provided that gnu ls does not use same flags as ls-lisp
with different meaning.
