Indeed it does. And don't forget that the most basic data object in the routing table, the address itself, is 4 times as big.
Let's also not forget, that many organizations went from multiple allocations to a single allocation. If we all filter anything longer than /32, we'll rearrange the flow of traffic that many over the years have altered through longer prefixes. Even I suspect I may occasionally have to let a /40 out now and then to alter it's traffic from the rest of the aggregate. Traffic comes to you as it wants to come to you. The only pseudo remedy that currently exists is to move some prefixes over to a different path. If you only have a /32, that'll be a bit hard.
This, more than anything, is what will effect this list and the people on it where IPv6 is concerned. Filtering longer than /33, 35, 40? Dare we go to /48 and treat them as the new /24? I know for myself, traffic manipulation can't begin until /40 (unless I split them further apart).
