Good idea, but judging from the increased trend to de-aggregation of
existing subnets in order to allow multi-homing of PA-subnets, I doubt
that there'll be many people interested, given the (usually) necessary
work that has to be put into renumbering ... while going against the
trend with this suggestion might be nice for the overall community by
saving some memory on all of our routers, the advantage for the ISP or
person returning multiple subnets for a larger one is (usually) rather
small ... if, of course, RIPE would incentivize by - e.g. - returning a
/21 for 6 /24's, I guess some people might be interested ;) But then
people not that "lucky" to have multiple small PAs would complain, as
would (rightfully so) the ones interested in conserving IP addresses ;)

Also, isn't there some provision already for LIRs to be able to return
subnets for a another?
