If I had 32 departments and were wanting to give them equal sized allocations then I'd give them a /53 each which is 2064 subnets each. It isn't that hard to do 8 delegations in the reverse tree for each of the 32 departments. Delegation on nibble boundaries is for convience and nothing else.
For comprehensibility which nets convenience. Consistently delegate on nibble boundaries and your power users don't have to understand Boolean algebra to make sense of the network.
Hexadecimal is much much simpler than decimal to work with on non nibble/octet boundaries. I think most people are applying IPv4 non octet experience to non nibble IPv6 addressing. The two are nowhere near comparable having had to work with both.
