Exactly, many previous unsuccessful discussions at IETF about 240/4: IPv6 is the only viable long-term solution.
The effort to “reinvent” any part of IPv4 or patches to it, then test that everything keeps working as expected, versus the benefits and gained time, it is much best invested in continue the IPv6 deployment which is already going on in this region and the rest of the world.
It would not make sense, to throw away all the efforts that have been already done with IPv6 and we should avoid confusing people.
I just think that even this thread is a waste of time (and will not further participate on it), time that can be employed in continue deploying IPv6.

IIRC, at some time, perhaps when CIDR was deployed widely and
having something other than IPv4 was a hot topic, there was a
discussion on releasing 240/4 in IETF. Reasonings against it were
that the released space will be consumed quickly (at that time,
NAT already existed but was uncommon) and that new IP will be
designed and deployed quickly (we were optimistic).

There have been many discussions about 240/4 in the IETF. For some examples, query “240/4” in the ‘ietf’ mail archive on mailarchive.ietf.org.
