That makes very little sense to me since the smaller providers can get
a /22 directly from ARIN.
Sometimes resources that come from a regional registry are not
welcomed by a national operator. This can go for AS numbers as well as
addresses. And sometimes a national operator is the only way out.
Not welcomed as in, filtered out / these providers refuse to route them?
Or do they kick up a fuss on the lines of "you should approach only
me, or failing that the LIR, for IPs, don't let me catch you running
to the RIR next time"
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.
