Clearly.
If Emacs can suddenly start supporting it then Emacs can
provide a way to turn it off (it was, in effect, off before).

Yes, thank you.
There shouldn't be any need for turning off bracketed pasting. It's just a separate input key sequence that is either sent or not sent by the terminal emulator. This isn't different from e.g. the Hyper key; there's also no option to disable the latter.
The issue here is that the terminal emulator sends various escape sequences to the running program; such escape sequences cannot in general be used as custom key sequences, because they are intended to have a special predefined meaning.
