The lack of a chicken is not an argument against the use case for an
egg.
But in any case, Bizgres was exactly this case, so they already did. We
just forced the authors to produce a code fork to do it, confusing
people rather than attracting people to Postgres.
Are you referring to the bitmap index patch? IIRC, there was some
non-trivial changes to indexam API in there, as well as issues with
VACUUM. If anything, that patch supports the assumption that anything
that needs WAL-logging is working at such a low-level that it needs to
be in core anyway.
