You say waste, I say perfectly valid use.
Its waste to carve out of that many subnets without a good reason (and no the reason presented so far are NOT compelling, IPSEC works perfectly over a bridged interface).
If you're dealing with business customers, then your usage versus wasted ratio is much higher and less of a concern, but what's the point? Are you trying to cut down on a large broadcast domain?
Why is it less of a waste to allocate a /30 to a business using a single public IP than it is to a residence? This makes no sense to me.
I simply prefer the additional troubleshooting and other capabilities given to me in a routed environment in most cases.
If you want that then you need to run a router not have a /30 routed over your WAN interface. Its far better for your WAN interface to be part of a much larger subnet that we can in turn route a network to.
