The motivation seems more along the lines of "denigration" vs
deprecation. But even if so, I agree with Hans's implicit claim that
it might be better to thoroughly document all the issues encountered
when using finalization and/or PhantomReferences and/or cleaners, etc.
This coverage will necessarily convey the high expertise required to
implement and use them effectively, and to not use them otherwise.
Currently no single authoritative account exists, so a lot of
errors are due to confusion or ignorance. Doing better would seem
to be the highest priority. But maybe adding deprecation warnings
on top of this will have some beneficial effect. So, like Hans,
I'm not completely opposed to this, but not excited either.
