Are pancake primes extinct ?

I'm sorry, I can't tell if you're mocking me or agreeing with me.

In either case, I'll elaborate my point a bit: I think Olympus in particular are making a point in their marketing about lenses being fast and silent for video use, and I think it's reasonable that they see it as a design goal that their lenses are "MSC" or what the Panasonic equivalent is. I was very careful not to talk about what you, I or others would find exhilarating or disappointing in a lens.
