The intent of the "Specification Required" requirement for registration is
that sufficient public information be available to allow an interoperable
implementation. Specifically, the text says:

https://tools.ietf.org/html/rfc8126#section-4.6

   For the Specification Required policy, review and approval by a
   designated expert (see Section 5) is required, and the values and
   their meanings must be documented in a permanent and readily
   available public specification, in sufficient detail so that
   interoperability between independent implementations is possible.
   This policy is the same as Expert Review, with the additional
   requirement of a formal public specification.  In addition to the
   normal review of such a request, the designated expert will review
   the public specification and evaluate whether it is sufficiently
   stable and permanent, and sufficiently clear and technically sound to
   allow interoperable implementations.

I don't think that a for-pay specification meets that threshold, though I'm
not aware of any IETF-wide policy on that (although I may just have missed
it).

In the absence of that, it would as stated above, be on the Expert to
determine
the standard.
