I agree with that goal.  However, that's not what the proposed 
policy says.

I suggest text like this, to make the wording better match the 
intent:

    This proposal allows an organization to receive an IPv4/IPv6
    allocation or assignment and/or an AS Number purely for
    anycast or GPRS Roaming Exchange (GRX) usage.  The usage must be
    in line with industry best practices as described in
    BCP126, BCP169, or their successors.

The "or their successors" part is what makes the policy 
automatically follow any newer BCPs that update or obsolete the 
older BCPs.
