Vint,
My response is a _double_ NO.
- NO to the legitmacy of the question itself.
- NO to the DISALLOW for pure technical reasons.
since you want this to be explicit and you are yourself explicit on
the reason of the consensus of this WG:

This makes the call for consensus outside of the WG scope as the
Charter says: "There are a variety of generally unsolvable problems,
notably the problem of characters that are confusingly similar in
appearance (often known as the "phishing" problem) that are not
specifically part of the scope of the WG".

I am not aware of a such a decision. I am not aware that TATWEEL is
not used in written language (I do not even read Arabic). I do not
see this is the charter which speaks of the support of the use of
"characters other than Latin A(a)-Z(z), digits 0-9 and the hyphen ("-")"

The charters says: "It is recognized that some explicit exceptions
may be necessary in any case, but attempts will be made to minimize
these exceptions."

That question is meaningless. (1) There cannot be a rough consensus
that it serves no useful purpose for domain names since only Arabic
script users can say it. (2) And even if there could be a real
informed consensus on that, this would have no impact what so ever on
IDNA2008 due to the charter of which I just quoted. This is an
exception among many others the members of this WG are just not aware
of, in many other languages (for example what about French half and
quarter spaces?). Our duty is to attempt to permit users to address
TATWEEL like cases on a general basis.
I have no objection if people in this WG wants to revisit the charter
and start working on IDNA2010, but please, let first complete and
publish IDNA2008.

The point is not to further restrict. The point is to support the
"characters other than Latin A(a)-Z(z), digits 0-9 and the hyphen
("-"), with the provision that if some explicit exceptions may be
necessary in any case, [] attempts will be made to minimize these exceptions."
If a registry wants to support TATWEEL it MUST be able to do it.
Hence my NO to DISALLOW.
If a registry does not want to support TATWEEL, it also MUST be able to do so.

It is your priviledge to confirm such a sense of the working group as
a rough consensus about its linguistic authority; that it does not
violate its Charter, nor fails RFC 3935 criteria when disallowing
TATWEEL at protocol level. In such a case, I think it would be
necessary to explain the rationale of all this when entering the text
documenting that ban: why TATWEEL and only TATWEEL.
Cheers !
