Yes, because that's such a common and well-working configuration. Only
lesser Linux distros will do this anyway, and they don't matter. How
many other changes did we make and ignore such issues completely?

You also forget that pre-bump libavformat was still supposed to generate
merged side data, because otherwise it would "break" applications. So
basically the BS was rubbed in my face.

Yes, it would be an improvement over doing complicated work for
absolutely no reason.

I lost much of those.
