Can it?
If not, we must require it in the specification.
Actually, now that you mention it, it would make sense anyway to add
some note to the specification on what exactly compressed with zstd
means.
So, we don't know do we want one frame restriction or not. Do you have a
preference?
I'm a fan of 'be strict in what you produce, liberal in what you
accept'. While our implementation always produces only a single frame of
compressed data, I think our decoder should be prepared to see more than
one frame from other implementations, as that is more liberal than
tightening the specification to require that encoding must produce
exactly one frame.
