48's is not a good idea, but giving an LIR
It does make sense to give the LIR a few bits.
Note though I say what "should" happen.
What will happen in actual fact, is probably going to be identical to IPv4=

End users will go to other ISPs and demand they carry their individual /64s=
;
resulting market pressure is more powerful than efficient design.
