I imagine they'll become a tad easier to find if NEC 2008 requires them!
This seems no different than any other new code- NFPA identifies a safety risk that can/does cause death or injury, and mandates a technological fix, even if it create a nuisance. Yeah, it will cost a boatload more than the 50-cent contractor specials we're used to, but so does GFCI and AFCI protection. I'd argue that if it saves even one life in the next two decades, it's worth all the cost and effort.
