TPIA examples are even more complex, as they deal with more granular buildouts. 2014-20 should not attempt to simplify this, as there are operational realities that should not be ignored.
David -
If we're talking about transfers (as opposed to allocations from the
IPv4 free pool), couldn't those "operation realities" be addressed by
using a lower utilization threshold than 80% for qualifying for a new
transfer?
I am not for or against the present approach, but want to understand
the community thinking on why enterprises should be prevented from doing
transfers and subject to architecture-specific constraints in order to
receive approval. I have heard concerns expressed about risk of brave
parties engaging in 'hoarding' but is that realistic if the constraints
are relatively easy to comply with but still prevent a hard upper limit?
One might argue that more aggressive constraints actually encourage
folks to hoard, i.e. once you decide to go outside of the registry
system, there would appear to be every reason to maximize the size
of any transaction without regard to registry policy limitations...

Yes, this has been the existing practice. I am also personally and
painfully aware that prior to DHCP, IP address assignment within a
local network was done manually, but do not see many folks continuing
that practice simply because of that history...
If there are to be constraints on transfers to new entrants, I will ask
the same question as above - is it better than they be based on directly
evidenced need (equipment and customers in hand) or based on speculative
assertions of future need? ARIN staff can verify a forward-looking plan,
but in the end, it is verification of intentions rather present state of
affairs, and that limits ability to anchor approvals to verifiable data.

Would that be solved by a "33% or 25% utilized on receipt" criteria,
or is the present linkage to IP initial assignment policy superior?

You've make some passionate arguments for maintaining manual processes
for transfer review based on forward-looking assertions of applicants;
effectively maintaining the for approval regime used for space issuance
from the free pool indefinitely for transfers in the future. Do you see
(per the proposal intent) any opportunities for simplification of present
transfer policy, either by changing the existing proposal or otherwise?
Thanks!
