I would be loath to take such a sanguine attitude, however.

The UTC first took up this issue formally on April 29, 2000
(document L2/00-139R) when the UTF in question was referred to
as "UTF-8-16". At that time there was some discussion, a great
deal of it opposed to the introduction of another UTF. At that
time, the Peoplesoft representative was tasked to go off an
"summarize the database issues" that underlay the proposal.

After much delay, the issue resurfaced in this last UTC meeting,
as UTF-8S, with some of the concerns addressed and more background
presented about the database performance issues that have been
driving the proposal.

*This* time the reception was not as hostile as a year ago, with
something like a 50/50 split in the committee, and with claims
forwarded in committee that "there is near-universal agreement
among the database vendors", with the noted exception of NCR.
There was a consensus to take no action now, and the Oracle and
Peoplesoft representatives were tasked to make further revisions
and perhaps bring in database specialists to discuss the implementation

The point is that while the UTC did not endorse this proposal as
of May 23, 2001, the pressure to create a UTF-8S is rising, and there
is no guarantee that the UTC will not sway to such support in
the future, despite the logic of the arguments presented against
