I don't consider filtration of bogons to be routing policy so much as a
mechanism to enforce addressing policy.  If it is a matter of addressing
policy to claim that "these addresses are reserved for purposes not
including routing on the global internet", then, it is a matter of addressing
policy to be able to rely on some mechanism to prevent that, or, recognize
that such an addressing policy is unlikely to be respected.

I don't object to NCN.  I object to NCN on different terms from GUA which
encourage the possibility of abuse of the NCN which would degrade the
utility of NCN for either the NCN purpose or the "it's not usable as GUA"

Actually, I don't care what you do behind closed doors.  However, if
it's truly behind closed doors, then, you don't need to globally coordinate
it, you can create a registry behind those same closed doors to handle
it.  What I'm saying is that if you want ARIN and/or the RIRs in general
involved, it should be done in such a way that it does not become a
well known easy path to end-running GUA policies set by the RIR system.

I'm not trying to do any such thing.  I want GUA to be easy and cheap
for all.  I want it untied from routing.  I want to offer GUA and GUA
tainted on the same simple terms of justified need.

No such thing.  I just don't want to stupidly break global addressing policy
in the process.  If you want to do something stupid behind your own closed
doors using your own registry, feel free.  If you want to do something
stupid in a globally unique way that is guaranteed the ability to be perceived
as harmless to the internet while doing great actual harm, then, I have
an issue because that's not stupid people doing stupid things to themselves,
it's stupid people doing stupid things to everyone else while feeling no
consequences themselves.  In general, policies that allow such actions
do not lead to good stewardship.
