Lorwyn and Morningtide came close. In that block, the strong tribal theme tended to push creature types into one of the eight relevant tribe buckets. But in general I think settings benefit from showing a variety of different creatures, both sentient and non-sentient. Beasties and monsters are great at creating the feel of a detailed world with a complex ecology. Also, beastie and monsters are great! Rawrrr.
Well if you think about it lorowyn had all the sentient races because of the changelings :)
