I am ok with this, but would you then say that the semantics of LPM are an integral part of encoding location information in the IP address? (and subsequently, IP addresses were not locators prior to CIDR?)
Well, strictly speaking, LPM predates CIDR. Yes, for an IP address LPM (and the full routing table) is definitely part of what encodes location.
I think I agree from a definition perspective - that is - we can make use of proximity semantics in the address space even if there is no aggregation in the routing system. However, from an engineering perspective, the only reason to employ such semantics in the address is if you plan to aggregate (somewhere/somehow), right?
The clear purpose of hierarchy is to achieve scalability through abstraction.
