As you're aware, RFC 2050 was a group effort, so focusing on Jon's intent seems questionable particularly given he sadly isn't around to provide corrections.

My recollection is that all of the authors recognized that attempting to deal with what is now known as legacy space was _extremely_ controversial and was wildly unlikely to have reached any consensus, particularly in the context of how the IETF works and the then ongoing battles regarding CIDR deployment and its implications. Instead, we consciously focused on merely trying to document the then current practice for allocations and assignments.  Even that turned out to be a prolonged nightmare, especially trying to get it through the IESG (which discouraged further attempts at trying to use the IETF to derive addressing policy).

In other words, since RFC 2050 merely attempted to document then current practices, it intentionally did not address (pun intended) allocations made prior to the establishment of those practices directly.  Rather, it merely noted that future allocations or assignments would take existing holdings into account.

With regards to specific language, you reference section 2.1.1.  You'll note that this is in a section talking about guidelines for how ISPs should deal with address space.  It is saying ISPs should treat assignments to their customers like loans. Section 2.1.3 is talking about two different things as indicated by the terminology used.  The "future _allocations_ may be impacted" is talking about allocations made from the RIR to the ISP.  The "existing _loans_ may be impacted" is saying the RIR could ignore assignments the ISP has made to its customers (making it a bit difficult for the ISP to get new space).

So, if you believe ARIN policy applies to all space, you're saying that ARIN at one time violated the section of RFC 2050 you quoted and that later, ARIN changed that policy.  This sort of policy evolution is exactly what was envisioned when we wrote RFC 2050.  We assumed policies would change over time, and as such RFC 2050 was merely documenting the current practice as it was in 1996. This is why I always find your referencing 2050 as if it is sacred text curious.

In thinking about this, since RFC 2050 was focused on IPv4 allocation policy and there is no more IPv4 to allocate, 2050 should probably be moved to historic.
