If you can eat it, then so can a lot of other critters. The rabbits, possums, and squirrels quickly figure out you're the Grub Hub of the neighborhood. The crows will join in, too. There's nothing inherently wrong with that, but if you think you're growing food for you to eat then boy are you in for a surprise!

Also, most lawns I've seen will inevitably have clover, unless you're overly aggressive with your herbicides, which most people aren't. The pollinators are supported, not that that really helps anything since they're not commercial pollinators.
