I have a specific question on the "too late to be commented" n4458 FDAM
document. It concerns cuneiform numbers, and more specifically the
absent CUNEIFORM SIGN U U (aka cuneiform 20)

This "missing" character has been discussed here last year, and Ken
Whistler gave the rational for several related encoding decision here
http://www.unicode.org/mail-arch/unicode-ml/y2012-m04/0177.html and
stated that the omission of the character was voluntary, citing a
document by Steve Tinney.

Since then, it has been proposed by Steve Tinney and Michael Everson in
http://www.unicode.org/L2/L2012/12207-n4277-cuneiform-add.pdf as
U+12399. Steve Tinney is also author of a page at the ORACC project
http://oracc.museum.upenn.edu/doc/builder/math/ where this character is
listed in the "stacking patterns need[ing]" to be added to Unicode,
among others which will be added as U+12469 and following.

However, this character 12399 is absent from the ballot, which stops the
additions in the cuneiform block at 12398. What is the rational for
omitting this character ? Stability with "legacy" encoding (i.e.
pre-unicode 7) ?
