That was considered, but rejected. It may be a good policy at the
registry level, but there are exceptions that need to be made
for certain character combinations in certain scripts.

 >01234... are sometime called arabic digits and belong also to arabic 
script (used in western Arabic countries). www.UNIV5.ma, where UNIV5 are in 
arabic, would be wrong?

That would be wrong, but not because '5' is in the wrong script.
It's because IDNs prohibit mixing of RTL and LTR scripts in the
same label (still no problem in this case), and require an RTL
label to start and end with an RTL character rather than with
a neutral such as a number. This restriction was necessary to
make sure that the display doesn't get messed up.
