"is that necessarily a bad thing?"

Yes.

The value of the diversity is not just aesthetic.

Human laguage is rich and expressive, matching human thought. The diversity is part of the expressiveness. Saying something in some poetic, or merely different way, is not just an inefficient or ambiguous/confusing way of saying the same thing, it's saying something else, and that something else cannot be expressed any other way.

A crayons-only, thumbs-only, Apple one-button-only, 1000 word vocabulary world is not efficient, it's poor.
