DPF really sucks. Anyway, those newer ceramic glowplugs and exhaust variable valve timing (emulating a non-cooled EGR) are also useful since they provide quicker warm-ups, and newer standards for Diesel fuel with higher cetane ratings also generate a lesser amount of heavy particulates to clog the DPF. What bothers me is how the automakers compromise the efficiency and adaptability to alternative fuels to go cheap on those emissions aftertreatment setups which are a plague even when running on regular Diesel fuel.
