important to note that the motivation for releasing the cosmological principle, is that we know that there are "small" voids and that there is strong evidence of much larger voids and structure on the scale of tens of billions of light years that is incompatible with the cosmological principle, so it's not just a thing to do on a whim, it's supported by observation.
