There is no need for NAT in order to multiple-home. BGP is every bit as effective and much simpler.

I know a lot of small businesses with one FiOS link and one Comcast
link and I don't think they're going to be able to do BGP. Their
providers won't do it and their prem equipment doesn't support it and
the local IT person doesn't have the know-how to do it.  I know that
the typical NANOG member isn't in this category, but this is a
use-case that is very common and outnumbers NANOG members.

building a cpe that can do something useful with two ip addresses and
two default routes to two consumer isps isn't really that hard, had a
cisco 2500 circa 1995 that did dial on demand for backup... heck, today
you can get a cradlepoint with 3 x 3g/4g wireless cards attached.
