Guess someone needs to write a draft with BCP regarding this, or perhaps
extend the protocol to include that the requestor can ask for a preferred
size (or do multiple /64 PDs).

I see no problem with sane defaults solving that problem.
Now, if every ISP now adhered to handing out at least a /56 to each home,
sane defaults could be created. If each ISP does it its own way, sane
defaults won't work.
So just hand out a /56 or /48 and be done with it. Your idea of chained
/64 doesn't really solve anything that couldn't be solved with a /64
default PD handout in the home gateway as far as I can see it?
