You got it pretty much right on except for that little tid bit.
The only things we don't spec in metric anymore are things that cost more to purchase in metric. Now.. we model them in metric units, and use metric dimenions on prints. FEA is also done is metric. But the understanding is that it's still an imperical dimension.
Very few things are like this anymore though. About the only thing I can think of at the moment are hoses & some bearings.
