What is missing in a pickleball paddle?

I’m curious to know after hearing from many people most pickleball paddles see standard shapes and sizes. From performance perspective is there anything anyone would like to see in a paddle? Anything that you have thought of but have not been able to find? Curious to know personally I wish for all around paddles to become more mainstream seems a lot of people note that there is always a trade off whether it be good power, spin, or control can’t have it all. Is there anything else you have thought paddles should incorporate but don’t?
