a truly radical proposal
RIRs refuse to grant ASNs to dual-homed leaves. Transit providers _must_ cooperate with each other. Hopefully they coalesce joint ASNs and space responsibly before sending such merrily along to the global table.
Voici, non-portable ASNs and "minimum height to ride" requirements for a portable, personal ASN. This really isn't much more restrictive than today's policies, and changing an ASN is easy for small leaves.
The biggest pitfall I see:
Imagine having to renumber when _any_ upstream changes. I propose that this is reasonable for > /24, where such is the status quo. For <= /24 non-PI space, one could use non-coop space from a specific upstream -- again, the status quo.
On a related note:
Someone pointed out off-list that the "coop ASN" approach requires creating a new ASN when one changes providers. Yes, but this still uses no more ASNs (unused ones are returned, right?) than if each leaf registered its own portable ASN.
