How long should addresses be? 256 is good, lets you encode a whole ec25519 key. 512 for expandability? 1 megabyte for post-quantum?

Why cap it at all?

If you can process 512 then you get access to those, else you don’t.

Let the free market decide where it’s comfortable like it did with wireless security.

What good is a standard if it doesn't make devices interoperable?

		Catcher pitcher model. Pitchers pitch, catchers decide what to catch. You want access to the 512 space, pick up the 512+ capable device. Free market decides where it lands. If there’s nothing of value at 512, it’ll naturally flop.
