I strongly agree.

The first level of abstraction is the start_ip and end_ip of inetnum 
objects. Rules I think must exist:

- inetnum objects must exactly match a NET object in ARIN Whois
- inet6num objects must exactly match a NET object in ARIN Whois

No inetnum or inet6num object may be asserted in ARIN IRR if it does not 
already exist in ARIN Whois. Why? Because this is how "bad actors" have 
abused RIPEdb and other wide open IRRs to perform one critical function of 
setting up a malevolent operation.

RIPE's db-wg has been having this discussion, and there is very clear 
consensus on the rules I propose above

The second level of abstraction is authorization. As Jason writes:

A rule that I think would make sense:

- maintainer objects are always authorized by the ORG objects in Whois.

This is obvious.  What is less obvious is that you want to authorize 
scripting to ADD/UPDATE/DELETE objects under your maintainer. So something 

- While authorized contacts can add NIC handles to maintainers, 
notifications (notify:) for the maintainer object must always be sent to 
the current ORG pocs to ensure they are aware of changes.

Now Jason brings up data integrity

Agreed. But with forewarning.

Absolutely, and obvious to everyone I hope.

Gotta speak up here for "more traditional".  Every operator I've ever 
been at still does this the old and reliable way: email, with cryto
signatures.   At scale, it makes sense to have an API for all this, and 
leverage the API KEY infrastructure already in ARIN Whois.  But for 
discrete changes (which affect the majority of IRR users), email needs to 
remain an option, in my opinion.

Ding ding ding!  Nice thinking, Jason.

No.  There is no need for IRR to worry about multiple parties.  Just like 
SWIP, if authorization exists, authorization exists.

The autnum and related objects need some real discussion here. Like Jason, 
I suspect the answer is maybe, but I don't know enough to know.  I can 
rope in experts into this thread if you need us to.

Disagree here, because if the route object is valid, the IRR doesn't need 
to authorize the AS relationship.  But that's all part of "the autnum and 
related objects need some real discussion here".

> 3.c. Should a route holder be able to remove an origin AS from their

Didn't grok the situation you're describing.

Yes but same as above.
