I don't know when I would ever want to actually do this in practice, but allowing the ?. operator to magically effect code outside of the parentheses definitely counts as "spooky action at a distance". Guido's rule of "everything to the right" is easy to reason about if "to the right" ends where the parenthised expression ends.
We already expect "to the left" and "to the right" to end based on operator precedence rules. Parentheses are used to control operator precedence. It would surprise people *greatly* if they didn't bound the effect of the question mark.
