IANAL (although I do often stay at Holiday Inn Express), but that's not how
I read it.

LRSA signatories agree to be bound by all ARIN policy except where
specifically superceded by LRSA terms themselves.  I don't see such a
superceding clause excluding revocation by current or future policy.

If ARIN were to revoke all legacy registrations by policy (without
mentioning an LRSA exclusion)... poof.

Indeed, if ARIN were to make or change any kind of policy under which some
LRSA registration was then subject to revocation...  poof.  The unlikeliness
of such actions might be extremely low, but as long as the mechanism exists,
I think this kind of exposure is what makes legacy holders reluctant to sign

I've been suggesting that the LRSA explicitly do what it sounds like you
feel it already does, that is, assert that protection explicitly.

If anyone can correct my understanding of the language in the LRSA, to the
effect that does indeed protect against this concern, I would be thrilled to
learn about it.
