It's not "no problem" at all. I, for example, want to know if two addresses are the same. With IPv4 I look at them, do strcmp or simple 32 bit integer arithmetic; with IPv6 I have do do a massively complex normalisation step first then line them up on paper and use my fingers.
IPv4 addresses (without CIDR) can be understood by humans in their heads. IPv6 ones can't.
