Nobody would allow that to happen. Once it goes RFC1918, it would never
go back.
Adding four /8's to the IPv4 RIR assignable space (as you suggest) isn't
buying anyone any time before we run out.
The effort someone would spend figuring out if 204/4 is reachable and
not-pain-inducing in their infrastructure is better spent figuring out
how to make IPv6 work within their sphere of responsibilities.
