Yes, but, that utilization can be documented need for X hosts to be numbered in an initial
deployment, it does not have to be X existing hosts numbered from some other set of
resources. It can also be made up of hosts numbered from RFC-1918 space which now
need globally unique addresses for whatever reason.

Not all that rare, but, yes, relatively rare.

I'm not sure. I know that I have no trouble getting appropriate sized assignments for
my end-user clients with appropriate justification of their needs without them necessarily
having existing space from ARIN or any other entity.

I know that the ARIN process can, on occasion be tricky to navigate if you don't
understand the subtleties of how some of the terminology is defined and that people
often use terms which have very specific meanings to ARIN staff members to have
a much broader meaning in what they are intending to say. I know that often leads
to misunderstandings which make the process even more difficult.
