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.
