Policy-based routing is evil? Discuss.

I'm having a discussion with a small network in a part of the world
where bandwidth is scarce and multiple DSL lines are often used for
upstream links. The topic is policy-based routing, which is being
described as "load balancing" where end-user traffic is assigned to a
line according to source address.
In my opinion the main problems with this are:
- It's brittle, when a line fails, traffic doesn't re-route
- None of the usual debugging tools work properly
- Adding a new user is complicated because it has to be done in (at
least) two places
But I'm having a distinct lack of success locating rants and diatribes
or even well-reasoned articles supporting this opinion.
Am I out to lunch?
