This is one reason I like the term Minimum Desirable Product better than the Viable dito.

I don't consider an undesirable product to be viable so I think "viable" still works.

I'd agree, but I have found people get confused on that point. Of course, I worry with "minimum desirable product" they'll miss the "minimal" bit.
