Sucks to be them. If they do not have enough PA space to meet the RIR minima, the community has decided they're not "worthy" of a slot in the DFZ by denying them PI space.
Not true, there is an ARIN policy that allows you to get a /24 from one of your providers even if you only need 1 IP address:
NPRM 4.2.3.6
"This policy allows a downstream customer's multihoming requirement to serve as justification for a /24 reassignment from their upstream ISP, regardless of host requirements."
If the PA /24 is under 199/8 or 204-207/8, then the filters being discussed would allow their advertisement through, because ARIN's minimum allocation for those blocks is /24. In ARIN's 22 other /8s, the filters would not because the minimum is /20 (or /22, for 208/8). Let's also keep in mind that if other folks block a PA more-specific, the site doesn't lose connectivity unless they lose their upstream connection to the LIR that assigned them the block. I suspect that many of them already see that behavior today, at least partially; we're really discussing making it a near-complete outage versus a semi-outage. That's life if you don't qualify for a real routing slot via PI.
