> 1. Only allow base buffer to have parsers, no change is needed for insdel.c, treesit_record_change can find the base buffer and update its parsers. We can ask indirect buffers to use their base buffer’s parser. Unless the base buffer is narrowed, I think it will work fine. 

I think this is fine, but we need to document it.

> I remember that there were a discussion along the lines of user-narrow vs low-level narrow, what was the outcome of that discussion?

Nothing in particular, and I don't think it's relevant.  If some mode needs
to widen, it can.

Thanks.
