Is the Zinc necessary with the newer engine components?

Of course!

Zinc's only worth a hoot for flat-tappet cam applications. It's wasted dinero for roller (hydraulic and solid) cams.

Sometimes a distributor gear likes to have a little ZDDP to fall back on....

I buy conventional oil with ZDDP in it for my roller cam, but it's just a matter of helping me sleep at night. I have no idea if there is any benefit.

ZDDP is a lubricant, right? I fos, you would surmise that it would lubricate more than just flat tappet cams, but then new cars don't require the ZDDP.

Yes. ZDDP is the acronym for the zinc/phosphorous combination that is really what we're all talking about. It is absolutely wonderful stuff, but it is toxic to catalytic converters. If we didn't have catalytic converters to worry about you'd still have a healthy dose of ZDDP in your oil as it acts as a "sacrificial layer" between metals when they come in contact with one another (and when there is insufficient lubrication there).
