Even if the CPE Router has a default router out the WAN interface to the SP router, RPF may support a knob where "Allow default route to match when checking source address" is not allowed. One can configure a router to disable checking the default route to match src-addr by RPF.
Aren't we talking about a single-homed router? On a mass-market consumer router with one logical WAN interface connected to a service provider's edge, how likely would such a knob be used? Asymmetrical routing is proably not a significant factor.
