Technically, its not even that, at least not as I understand it.
Legacy address space is space which was assigned prior to ARIN's
existance for which for which ARIN currently provides the registration
services (RDNS, Whois). The old /8's, for example, are not ARIN Legacy

Again, these registrations are already in ARIN-managed space. The
point here as I take it is that if there were some outpouring of
addresses that freed up /8s faster that ARIN registrants consumed
them, ARIN would return those /8's to IANA.

I respectfully disagree. The whole point is that if you don't sign the
Legacy RSA, your future is uncertain.

But then, perhaps that should be said explicitly: Legacy Registrants
who choose not to sign the RSA will be subject to whatever laws, ICANN
policies and ARIN policies are eventually enacted to deal with such

That should scare everybody into signing. :)
