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.

No it won't, you have a /40 with assignment size /56 and /64 and then how to specify which customer has what. Can't we solve this by allowing more specifics ?

The original thought was to just create multiple entries, one for each assignment size. But we could allow for something like:

bla:://40 -> assignment size /48
bla::1/48 -> assignment size /56
