Oh no, opposed pistons were very common in the locomotive diesels used in subs in WWII, Fairbanks-Morse was a famous one.

I should have remembered that. It powered a significant portion of the sub fleet in WWII.

Maintenance, one would think, 2X as many parts to fail. They comment on that in the wiki when they put the F-Ms in locos
There are fewer parts per piston than in a conventional poppet valve engine. More per cylinder, but given that a 3 cylinder opposed piston engine is equivalent to a 6 cylinder engine, the former is apples to apples.
