I briefly considered this solution.  The problem is that the current BGP policy
databases, as used by ISPs, heavily relies on AS numbers and regular expressions
that operate on AS_PATH strings.  I can't say for all, but for some ISPs the
size of
BGP policy database way exceeds the size of all other bgp data structures
including RIB
and hence is a real issue. Thus increasing the size of AS number 8 times to
its current size was quite questionable to me.  But it is for the WG to decide.
