Okay, so rule #3 does prohibits the TILDE because of backward

compatibility issues -- are there?
I believe so, yes. This issue was studied extensively during the
design of IDNA, and a large number of contributors have indicated
that absolute, 100% backwards compatibility is an absolute,
sine-qua-non requirement. IDNA would not have passed IETF if
there would have been the slightest indication that it isn't
fully, 100% backwards compatible.
3) is this just something that has not been, or will not
be, considered;
It hasn't been considered. Now that the RFCs have been published
and are already widely implemented, it is extremely unlikely that
it will be reconsidered.
Tell your friend he can unregister his domain - users will never
be able to type the domain name.
