Yes; this has worked in the past, and loss of this functionality is unexpected.

It seems to me that after a healthy post-deprecation cycle, and if we
choose to keep the Z/2 meaning of __sub__, it might be worth reintroducing
__neg__ as a no-op? AFAICT, this is consistent with the Z/2 interpretation?
