those are not jus flat tokens so I wasn't quite sure what to do about those, it seemed like maybe i should deep clone them?

I definitely don't have enough context on the workings of the checker to give any informed feedback, but I can at least ask at a high level do we have some confidence whether anything more could be done to the structure of the code to avoid this general class of problem?

Tbh, I don't know this part of TS too well either so we need to wait for @weswigham or @dragomirtitian to give some feedback on this. I'd expect that other things in this function (like node.attributes here) should be wrapped like this too (if only this is the right fix).

I would definitely suspect a lot of this needs this same fix.

100% - any child node we copy should have its' children visited - any missing visitor calls on manually remapped nodes are an oversight, presumably.
