In my opinion, it doesn't work when the extension is related to a 
specification defined out of the RDAP context but is used in RDAP such 
as JSContact or VCARD itself. In this case, a server can simply update 
the hint in rdapConformance to signal that a new version of the external 
specification is supported.

As a matter of fact, we have already done it (even if unconsciously) 
without either passing from "rdap_level_0" to "rdap_level_1".

I'm referring to the fact that the RDAP response format has indirectly 
been extended to support the VCARD CC parameter when RDAP responses were 
already provided by servers and consumed by clients.

Best,

Mario
