Doug, et al --
The primordial statement you're looking for is in TUS, Chapter 1 and has
been there forever. See:
http://www.unicode.org/versions/Unicode8.0.0/ch01.pdf
In section 1.1, page 3:
*Note, however, that the Unicode Standard does not encode idiosyncratic,
personal, novel, or private-use characters, nor does it encode logos or
graphics.*
I'm not sure UTC has ever made any specific pronouncement on the topic,
but they do sometimes add things to the notice of non-approvals, which
can generally be taken as a precedent.

If there is any such statement from the UTC, Ken Whsitler would probably
be the one who could put his hand upon it most quickly. :-)

I absolutely agree that UTC -- the technical committee, not the
corporation -- should issue a formal statement expressing its position
as to:
1. Generally, whether novel and untested concepts, particularly those
for which a sizable body of popular support has not been established,
are viewed by UTC as suitable and appropriate candidates for encoding in
the Unicode Standard, on the basis of their perceived future usefulness.
(I believe this statement has been made already; if so, a reference that
can be easily cited would serve the purpose.)
2. Specifically, whether the particular concept that William proposes,
to encode entities that are not characters into the Unicode Standard on
the basis of their perceived future usefulness, is viewed by UTC as
being suitable for and appropriate to the standard.
