> I guess “refactoring” includes not only whitespace changes but also some structural changes like slurping (or whatever it’s called), right? If you want to do structural changes, tree-sitter probably can’t help you much, as you observed. Maybe it’s better to “export” the tree-sitter tree to your own tree and do transformations with it? Maybe that’s already what you does now.

Or simply produce all the editing information up front, and then modify

Just like treesit-indent-region does.

That almost the same as described, but doesn't require creating a 
parallel parse tree hierarchy.
