It has to be unique so we can implement some basic rules on wether the assignment-size attribue is mandatory, other then that the exact naming can be anythingmwe like. I picked this becuase it makes sense to me.

No you shouldn't, probably as long as assignment-size > /48

I don't think so, especially since there is no requirement to register at all at the moment. So I can't tell if it's hijack r the space is actually in use.

But an extra status has not been required: on approval from RIPE NCC the LIR registers an inetnum with status "ASSIGNED PA". Why would an extra status be required in IPv6 world?

This one I don't understand. As far as assignments to end-users, it's usually implicit to be a /32. If any other cases exisit I wonder wether they are valid at all, but I'm not an IPRA.

This means that if the ISP has policies of, say,  /56 for most customers but /48 for some, while at the same time wanting to implement some form of per-PoP prefix aggregation, it means assigning multiple blocks per aggregation point, one per assignment size.
