My first problem is that it doesn't.  And it would be grossly
misleading to claim that StandardizedVariants.txt defined the variants
for Mongolian.  It states what variants exist, but not what the
variations are.

In principal, the omissions ought to be reported as ballot comment for
Issue 5 of ISO 10646.  I don't know whether the Mongolian chart will
be regenerated with the rendering corrections as a matter of course for
Issue 5.

I trust I have missed something, because it looks like an attempt to
sneak changes through.  I don't believe it is a good idea to change the
meaning of variation selectors.  If we can't use general purpose
variation selectors such as U+FE00 VARIATION SELECTOR-1, there is still
room at U+180F.

That is a welcome enhancement.
