Nice, thanks.

Now, concerning font-lock-ignore: why do you say you think something
like it is not needed in tree-sitter?  Do you see no need for a
fine-grained customization option for font lock, or do you have a better
implementation of fine-grained customization in mind?

I'd say a fine-grained customization option is very much needed.
Requiring the user to advice `treesit-font-lock-rules' is to high of a
bar.  `font-lock-ignore' may not be incredibly easy to use (the user
still has to look at the font-lock rule definitions), but it's flexible,
has a simple implementation, and imposes no extra work on the major-mode
developer.

You can probably just stick a call to font-lock--filter-keywords
somewhere in treesit.el and call it a day.
