My understanding of LRSA §10(b) ("ARIN will take no action to reduce the 
services provided for Included Number Resources that are not currently 
being utilized by the Legacy Applicant.") covered that.  That is 
certainly the intent, though I agree it could be more clearly stated.

In theory, we could pass a policy that revokes all LRSA resources, which 
_would_ ironically be binding on those that are unutilized but not 
binding on those that are unutilized, but I don't see even a remote 
chance that would ever gain consensus.  Still, if you want that 
protection explicitly in the LRSA, or my understanding above more 
clearly stated, that's a matter for you to take up with ARIN's counsel 
as input for the next revision.
