There are limits to the extent to which the community is willing
to continue the legacy free-for-all. Not having an RSA is outside
of those limits. The IPv6 will have to be covered by an RSA
anyway, so, covering the legacy space with a legacy RSA
doesn't seem a particularly high barrier.

There are two ways to approach this. One is to think (possibly
erroneously) that reclamation somehow delays IPv6 deployment.
The other is to recognize that it won't actually, but, reclaimed
space may be useful in easing the transition, and, eliminating
waste of space in IPv4 in favor of justified need based allocation
is probably a good thing regardless.
Obviously, I have my bias as to which is the correct answer of

Yep. Not actually a good idea.
