Can you clarify your objection to this idea? For me, the idea of having
IPv4 addresses as a 4-byte array seems to offer a lot of advantages over
treating it as a single 32-bit value. We don't need to worry about packing
or alignment of the values, and everything would always be treated in network-byte
order. The main downside I see is compatibility - we'd need a whole new set
of definitions and functions in libs to make the change.
