Hi Alvaro, 

Thanks for the follow-up.

What is really key is that DEs motivate their decision and work with requesters to make a request successful. DEs usually consult with each other, but I don't need to we need to have this in the text.

Below an updated DE text to reflect some of your comments. 

NEW:

   The policy for allocating new bits from this sub-registry is
   Specification Required (Section 4.6 of [RFC8126]). 

   Review requests are evaluated on the advice of one or more designated experts.
   Criteria that should be applied by the designated experts include
   determining whether the proposed registration duplicates existing
   entries and whether the registration description is sufficiently detailed and fits
   the purpose of this registry.  These criteria are considered in
   addition to those already provided in Section 4.6 of [RFC8126] (e.g.,
   the proposed registration must be documented in a permanent and
   readily available public specification).  The designated
   experts will either approve or deny the registration request,
   communicating this decision to IANA.  Denials should include an
   explanation and, if applicable, suggestions as to how to make the
   request successful. 

Cheers,
Med
