[arin-ppml] ARIN-prop-136 Services Opt-out Allowed for Unaffiliated Address Blocks

And note, by the way, that I am currently OPPOSED to this policy proposal.

But also believe we need a way to allow transfers to happen without risk 
to the seller in the case where the seller hasn't signed the LRSA. 
(Specifically, the case where one starts a transfer, signs the LRSA only 
because it is required for the transfer, and then the transfer fails to 
happen for external reasons... how can one un-sign the LRSA at that point?)
