However, to become an AS means that you have to be multi homed, i.e., have a connection to 2 or more providers. Since it is not hard to get a /24 from a provider if you are paying for a connection with them, then my understanding of the intent was that any ASN with two /24's should be able to get a /22. (I.e., for the microassignment, having an ASN was the crucial factor.) This is not the same as requesting an assignment for a /20 or smaller prefix, where different rules apply.
If you are an ASN with two address blocks, I think that you qualify and should apply.
It's not quite that simple. Suppose you're multihomed, have an ASN, and have /24's from several providers. But, you run all your hosts (perhaps several hundred or more) behind NAT except for a handful of necessarily public IP ones (DNS servers, web servers, mail servers, etc.). Say you've been given 3 /24's from 3 providers, but you only actually use about a /27 of public IPs. My understanding of current rules is that: 1) You don't qualify for PI space from ARIN (unless you're in the ARIN controlled regions of Africa). 2) 2 of your providers have violated the rules by automatically handing you a /24 with your leased lines as this is space you don't need and have no immediate intention of renumbering into. So, somehow its better that you announce 3 PA /24's into the global table instead of the 1 PI /24 you can't get.
