Do you think routers perform their work using the human-readable addresses?

If so, that is incorrect. They use the binary values. The actual difference between IPv4 and IPv6 is that IPv6 uses 128-bit addresses, not 32. So you can devise whatever human-readable abstraction you like, it won't change how networking actually operates.

And there’s no reason we should be limited to 128. It’s all just so dated and stagnant.

Chips can be made that dwarf that limitation, instead we’re stuck with this decade old nonsense to “work around” again.

Flip flopping between “the code needs it” and “the chips need it”.
