You don't actually understand program mode on a DSLR. It's actually like not having to switch from A to S rather than the old "I don't care what my camera does as long as my photo comes out" mode you get on point-and-shoots.

So depth of field and the way metering actually works aren't important?

Well, we can say "everything is important" and there's no sense to number this stuff to infinity. But if you insist: metering is also just a tool, which you can live without (using exposure value tables), knowing how exposure works is the core of photography.
