No, it's a lossless compression handled at the container level for the
specified track. It's perfectly fine to call it compression. There is a
"compression" and "decompression" involved, even though it's the most
basic possible (apart from null transformation). The name of the codec
is "Header Stripping".

No, I don't think so. Not worth the effort.
