Quite true, but the IPv6 address space is expected to be exhausted in 30 years. The switch from IPv4 to IPv6 is going to be painful, but that is nothing compared to what switching standard protocol stacks in the late 2020's would be like...!
You can always mitigate variable-length addresses by internal padding.
