(1) Stopped mixing the Host identification and the Network identification into the same bit field; instead every packet gets a source network address, destination network address, AND an additional tuple of Source host address, destination host address; residing in completely separate address spaces, with no "Netmasks", "Prefix lengths", or other comingling of network addresses and host address spaces.
Where's Noel Chiappa when you need him?
(2) The new protocol will use variable-length address for the Host portion, such as used in the addresses of CLNP,
This also was considered during the IPv6 design phase, and the router designers had a collective cow, as it makes ASIC design a whole lot more interesting. And back then, line speed was a lot lower than it is now... Not saying it can't be done - but you're basically going to have to do CLNP style handling at 400Gbits or 1Tbit. Better get those ASIC designers a *lot* of caffeine, they're gonna need it...
