> Dmitry’s idea sounds good, we can add a tree-sitter backend for show-paren-data-function, and make the backend for blink-matching-paren configurable, then add a backend for it that uses show-paren-data-function, which in turn uses tree-sitter (or we add a backend that uses tree-sitter directly). In either case, the tree-sitter backend don’t need to use narrowing and we are good.

Is this suitable for the release branch?  It sounds non-trivial, and
the problem is not very severe, to say the least.
