I'm far from sure how reasonable that is:  The introduction of
u+1E9E was discussed in public, but decided by a third party
not interested in its effects on the Internet, let alone IDN.

The Unicode list is not really public, e.g., it was removed
from Gmane.org later, and it is not indexed by search engines.
This is neither relevant nor public for practical purposes:

Disallow: /cgi-bin/ in <http://www.unicode.org/robots.txt>
is about the Web interface to the Unicode list archive among
other things.
