Of course, no one will be getting IPv6 terms under the same terms they
got IPv4 space for pre-ARIN. The main consideration for the legacy RSA
was that if someone wants to use IPv4 resources as a justification for
getting IPv6 space, the IPv4 space needs to be covered by some sort of
legal agreement. The legacy RSA accomplishes that, while preserving
nearly all of the legacy holder's rights to the IPv4 space.

Perhaps, but it's really more of a fairness thing. If you have legacy
space that's not fully utilized, and you'd like special treatment in
receiving IPv6 space, then ARIN can ask you to trade in your unused IPv4
space in exchange.

That's another valid approach. You could bring it up at the Open Policy
Hour, or discuss it here on PPML, and see if there's support for a
policy proposal to do so.
