Comment (by gjdfgh):

 >What container format to use instead?

 nut is the format that can store anything FFmpeg can handle (by
 definition, because the format is defined by FFmpeg devs and reflects some
 FFmpeg internals directly).

 >I expect Matroska to be able to store anything, one way or another.

 That's not true. There are a lot of things Matroska can't store (at least
 not in a way every player would understand). This doesn't mean Matroska is
 bad or anything; it's just a normal restriction for container formats.
 Sure, you could add a hack that makes FFmpeg alone understand your format
 "extension", but what value does it have if only FFmpeg understands it?
 The point of container formats is interchanging data in a standardized
 way, not a place for implementation to dump hacks.
