Registration request for new subtags for Portuguese orthographies

I don't see this type of screwing up in RFC 4646.

3.2 is all clerical and provides no "royally screwed up" checks and balances.

3.3 does provide:
   Maintenance of the registry requires that as codes are assigned or
   withdrawn by ISO 639, ISO 15924, ISO 3166, and UN M.49, the Language
   Subtag Reviewer MUST evaluate each change, determine whether it
   conflicts with existing registry entries, and submit the information
   to IANA for inclusion in the registry.

So the reviewers duty (besides the clerical in 3.2) is to ensure there are no conflicts with existing tags.

Also

   The Language Subtag Reviewer MUST ensure that new subtags meet the
   requirements in Section 4.1

In other words, it needs to be the right tag (nothing about whether the idea is worthy)

Further, in 3.5

   When the two-week period has passed, the Language Subtag Reviewer
   either forwards the record to be inserted or modified to
   iana at iana.org according to the procedure described in Section 3.3, or
   rejects the request because of significant objections raised on the
   list or due to problems with constraints in this document (which MUST
   be explicitly cited).

So, presuming there's consensus, the reviewer's duty is to forward the registration.  (However I imagine that if the reviewer objected there would not be consensus).

3.2.  Language Subtag Reviewer

   The Language Subtag Reviewer is appointed by the IESG for an
   indefinite term, subject to removal or replacement at the IESG's
   discretion.  The Language Subtag Reviewer moderates the ietf-
   languages mailing list, responds to requests for registration, and
   performs the other registry maintenance duties described in
   Section 3.3.  Only the Language Subtag Reviewer is permitted to
   request IANA to change, update, or add records to the Language Subtag
   Registry.

   The performance or decisions of the Language Subtag Reviewer MAY be
   appealed to the IESG under the same rules as other IETF decisions
   (see [RFC2026]).  The IESG can reverse or overturn the decision of
   the Language Subtag Reviewer, provide guidance, or take other
   appropriate actions.
