You can hand out /48 as easily with 6rd as you can natively. It's only when the ISP is lazy and encodes the entire IPv4 address space into 6rd thereby wasting most of the IPv6 address space being used for 6rd that a /60 appears to be generous.
You're contradicting yourself here. Yes, you're right about the technical solution, but it's not as easy (you need backend systems). Also, not all products support the variability of subnet lengths that the standard allows.
So if you're not mapping the entire space (actually some products only allow /32 IPv6 space) 1-1 you're making the whole solution harder due to complexity in your backend system plus you're limiting the amount of customer gear that will support the solution.
