Fernando,
A “single interconnection with a provider that requires a public ASN” is an example of a unique routing policy.
It is also an example of a technical need for a coordinated globally unique ASN.
However, you are correct in that the two things cited above are each supersets of the example you cite from the previous version of the policy.
As such, the new wording should make things easier, not more difficult.
> When it says "show a unique routing policy" doesn't necessarily mean two Transit providers (it could be an IX, a private peering to another ASN, etc), but excludes the possibility to have an ASN with a single Transit Upstream. On the second part that says "demonstrate a technical need for a coordinated globally unique ASN" what kind of technical need could for example be acceptable to justify to have an ASN with a single Transit Upstream provider (have their own assigned IP space ?) ?
> My concern is not to exclude de possibility for organizations to have an ASN even if they have a single interconnection with their Transit Upstream.

A unique routing policy is any situation in which a stub or transit autonomous system has a difference in interconnection from all other autonomous systems. As such, an IX, a private peering session, a cloud service provider which requires a globally unique ASN for BYO addressing, etc. would all qualify.
If you have a single upstream who requires that you have a globally unique ASN in order to use BYO addresses, then that is an example of a technical need.
In essence, any situation where you cannot accomplish your interconnection goals without a globally unique ASN is a technical need.
FWIW, the language in the current version of the policy is very similar to that which has been in use in the ARIN region for many years without any difficulty for organizations obtaining ASNs on any need.
