The Ethiopian binary multiplication is far simpler - it is now used in
computers. But now, the system is falling out of use, as it is easier
to let the computers do the arithmetic. (Besides, one has devised
fast, in the head, multiplication systems for base ten, as well.)

Nobody does, as there are already different systems in use. The
situation is the opposite: there is no need to promote one basis over
another as a part of a reform. Just use what is practical.

Anyway, Unicode just encodes actual usage, with few exceptions. If you
have some documentation, that may help your cause.
