So do you suggest/recommend that such crosses not be made?  Or is it just a
warning for someone not to get their hopes up if they attempt it?  Would
the seedlings inevitably be non-fertile (or barely fertile), or could it
result
in a fully fertile cultivar?

An arilmed x arilmed cross produces nothing but arilmeds?  Or could you get
some offspring nearly 100% aril and some nearly 100% TB?
