 ZDDP is in fact being removed from the engine oils, and there has been a corresponing increase in camshaft failures since the last drop in levels. That would put ZDDP in the same category as lead replacement additives.

Apparently, it is most critical when running in a freshly built engine, where camshaft failures have been reported after a few hundred miles. Has anyone heard of any problems with camshaft failures on the 900-series engines?
