That's not actually what the current policy document says. It's actual wording is:

   5.4.1. Assignment address space size

   End Users are assigned an End Site assignment from their LIR or ISP.
   The size of the assignment is a local decision for the LIR or ISP to make,
   using a minimum value of a /64 (only one subnet is anticipated for the
   End Site).

The old policy (ripe-412) had the reference to RFC 3177 that you have paraphrased.
But that recommendation has been removed and the only suggested limit is a
minimum value of /64. Apart from that minimum, the network operator can do
whatever makes most sense to their network and customer base.

So, in answer to the original question, 30m /64s is fine if that's what is needed and
30m /56s is fine if that's what is needed and 30m /48s is fine if that's what is needed.
There is a presumption of subsidiarity in the policy text, putting the choice into
local hands.
