For ISPs, that is very likely the case (due to policy.) Note this highlights
the potential issue for new ISP requesters, in that it is going to become (or
is becoming) increasingly difficult to qualify if upstreams do not provide
sufficient PA IPv4 space to smaller ISPs such that they can qualify for a
direct ARIN allocation later.

That's not readily apparent, but the number of IPv6 allocations to ISPs in total
so far this year is 237 <https://www.arin.net/knowledge/statistics/index.html>
so it cannot be more than about 60% of new requesters along requesting IPv6.

We can generate this is necessary; the mean is approximately 14 /24 equivalents
per new requester.

Correct - this is required as part of initial ISP allocations.

ARIN has no visibility into any of the above, and note that per NRPM 4.2.2,
standard ISP allocations are not required to return their blocks from their
upstream ISP (those receiving under multihomed policy are required to return)
