32-bit ASN acceptance by ISPs in ARIN region

I'd like to see an option for a larger private ASN block - 1K of private ASNs can be quite a pain in really large organizations.

I have seen others mention this in the past - e.g. 

But apparently there's not enough traction to cause movement.

hence my original comment about being usable on nontrivial transit networks, where having the size of the community local administrator >= your customer asn bitfield size is a rather useful feature.

There's also a serious vendor support problem at the moment.
