Expecting muxers to create broken files in cases where it can be avoided
is not something that should be done. Parsers for example were made among
other things to remove dependency some muxers had on decoders to get
timestamps and frame durations.
If i write a libavformat-based application dedicated exclusively to remux
files i expect it to create valid files, or fail if it can't.
In this particular case, changes to the muxer can fix the issue.
