I don't think the language definition should be judgmental here. The semantics are unambiguous.

Looks to me the prohibition was to prevent a crash. It makes more sense to fix it.
The crash can be fixed by just removing the check after finishing issue17611. But is there any use case for 'continue'/'break'/'return' inside 'finally' clause? The code like try: return 1 finally: return 2 or try: continue finally: break looks at least confusing. Currently 'break' and 'return' are never used inside 'finally' clause in the stdlib. I would want to see a third-party code that uses them.
