It is currently under discussion among the UTC members.

That is right, and it is good that you brought this to the
list's attention, because decompositions are precisely the
kind of thing which cannot be corrected after an official
release.

Not normative properties in general, but *some* normative properties,
and that statement merely reflects the decision that was taken
at the last UTC to stop updating some subset of the properties
as of March 7, 2006.

This, however, is flagrantly false. The first iteration of
UnicodeData.txt containing Unicode 5.0 data fields,
UnicodeData-5.0.0d2.txt, was posted on September 28, 2005
in the Public/5.0.0/ucd/ directory for public review, and went
through 7 more deltas, all publicly posted, by January 2006,
prior to the decisions taken at the last UTC meeting, which
resulted in the posting of the current delta, UnicodeData-5.0.0d10.txt.
The current beta page is for the beta 2 -- the second round of
beta review of the Unicode Character Database data files.

You may think what you want, but the beta reflects whatever
constraints are placed upon it by decisions of the UTC.

I'm not sure who the "you" is here.
By all means, please review the Ol Chiki and Cham proposals -- the
earlier the better.
Keep in mind their relevant statuses, however. Ol Chiki is
under ballot in Amendment 3. (And in my opinion, nobody -- the
original proposer, nor the UTC -- has missed any canonical
decompositions for that script.)
Cham is just a proposal at this date -- it is not yet included
in a 10646 ballot document, nor has it been approved for
encoding by the UTC.
