I can't say for sure whether this was the most common concern, but what I
remember as the main concern was that your proposal wouldn't actually do
what you want, but would create a great deal of work for the IETF and for
implementors, with no clear upside.

That’s actually a good test for whether it makes sense to do new IPv4
maintenance work, and I don’t think changing the balance on that is going
to be an improvement.
