In principle, I agree with you. However, my company (Zembu) has a
business need for better Oracle compatibility, based on real customer
need.

Zembu doesn't don't have a need to make Postgres a drop-in replacement
for Oracle; that is a nearly impossible task in any case, because
Oracle DBAs don't know how to manage Postgres, and most don't want to
learn. Zembu does have a need to permit applications to speak to both
Oracle and Postgres.

Just to be clear, I am not on the Postgres development team. I'm
talking about work which is important for Zembu, and which I believe
can be quite helpful to Postgres in general. I'm trying to structure
the work so that even if accepted it would not take too many cycles
away from core Postgres development.
