Right, so you combine the downsides of both approaches.

And it's unlikely to work here: for those standard size blocks, you
really don't want any per-user config: you want those to be assigned
automatically. But for the /48s you do need per-user config, if only
that this user gets a /48. So these two block sizes can't
realistically come from the same (sub-) range.
