Great recommendation.

Which is why we actually use them in the example in core-problem-details [1].

Our example [1] is:

  "tag:3gpp.org,2022-03:TS29112": {...

(The example is set in a 3GPP context, and this fictional structure is relating to 3GPP TS29112; complete with warning that they really should register an identifier for this.)
