A site needing more than 1 address... subtly implies different usage case scenarios... for different parts or different addresses on that block... which could slip back into... "you blocked my whole /48... but the spam was only coming from this tiny corner of the block over here (whether that be a one IP, a /64, or a /56)... and now other parts of the block that were sending out legit mail, are suffering". Likewise, sub-allocations can come into play, where a hoster is delegated a /48, but then subdivides it for various customers.
A hoster is a LIR. It isn't the end customer.
