[...] We still have the policy of not removing modules that exist in the Python 2 standard library. But 3.9 won't be covered by that :) I didn't even remember that. Where's that written down?

AFAIK, there has been no BDFL pronouncement or coredev vote. But it has become somewhat of a consensus as a result of discussions in multliple threads about removing modules going back to the 3.4 era.

PEP 594, just posted, proposes to codify a 'soft' (or perhaps 'slow') version of the policy: doc deprecation, code deprecation, and code removal in 3.8, 3.9, 3.10.

FWIW I am strongly in favor of getting rid of the parser module, in 3.8 if we can, otherwise in 3.9 (after strong deprecation in 3.8).

You could request that 'parser' be specifically excluded from the PEP, along with 'distutils' (and effectively anything else not specifically named). Or request that it be included, but with an accelerated schedule. I have a vague idea of why you think it harmful to keep it around, but a reminder would not hurt ;-).
