I think you read too much in the policy. The policy is very liberal
and intented to be that way. You can assign a /48 if there is a chance
that the end-user/your customer will need more than one /64. In fact,
it is recommended to assign a /48 in that case. However, it is not
required in any way.

Nothing will stop you from being more conservative than the
recommendations in your assignments as an LIR. Whether that is smart
to do is a completely different issue. What the policy describes is
the maximum amount of address space that you can assign to an
end-user/customer without getting in trouble with the RIR. You really
cannot get into trouble with the RIR by being more conservative than
the policy. Obviously, your customer might not agree with you being
more conservative than what is allowed and choose a different provider
if the end-user/customer has a need for more address space.

As for my personal opinion, yes I do think that the policy is perhaps
a bit too generous, especially in the case for more commodity style
Internet services like DSL/cable/dorm rooms/WLAN deployments.
Therefore, I think it would make sense to add a category for this kind
users which would broadly fit into what most people describe as "SOHO"
