That's for globally routable addresses, which you wouldn't get as nicely allocated in v4 either, if at all.

For equivalent of 10./8 space, you'd have ULA, which can be subdivided this way just fine (and arguably since fc00::/8 is left in limbo, you can use that. Or just decide to fit whatever addressing scheme you decide into 80 bits left after typical fd00::<48bit random>/48.

So sorry, your v4 strawman isn't too good either.
