Bridging emacs syntax to treesitter in a robust way seems like it could be a subtle enterprise, so I’d prefer to leave that to one of the experts.  Right now the syntax-propertize-function in python-mode does one simple thing: ensure triple quotes are properly marked as strings.  Since the treesitter grammar doesn’t distinguish between different flavors of strings, something similar would still be needed, if we want to continue to treat various string flavors distinctly using syntax.  

Is moving all syntactification (beyond just font-lock) over to TS an explicit goal for all the *-ts-mode’s?
