OK.

Adding a final argument that defaults to False doesn't
break the API for the callers, only for the implementors.

And if we drop the final argument, the API is completely
backwards compatible both for users and implementors.
The only thing that gets added is the feed() method,
that implementors don't have to overwrite.

Abandoning the final argument and adding a feed() method
would IMHO be the simplest way to do this.

But then there's no way to make sure that every byte from
the input stream is really consumed.
