As in, sometimes national operators will decline to speak bgp to (topologically) subnational operators, so that even when they present themselves with a regionally allocated public ASN and address space, these will not be accepted. I am not at liberty to identify specific cases, but if you look at recent-ish (RIR-era) ASN allocations that have never appeared in the routing table, you will come across (n) networks that fit this description.
Another reason to approach with caution proposals to cede greater registry-like authority to national PTOs and regulatory authorities, IMHO.
