We're dealing with a similar issue for the Decentralized Identifier
specification (which can serialize the data model into JSON, JSON-LD, and CBOR).

We wanted a .did file extension for each type, BUT were concerned that some
operating systems associate file extension w/ media type... and would become
confused and use the wrong handler if someone tried to double-click open the
file (as the encoding could be one of 3 incompatible types).

So, we went with the ugly: .didjson, .didjsonld, and .didcbor file extensions

Did we do the right thing? Not asking from a registry standpoint, but from a
best practices standpoint.
