Not really: The muxer does not write a value if sar == 0/1 (the field is not mandatory) but the demuxer always provides a value to the world. You could read the mkv specification in a way that this is correct (because a sar of 1/1 is the default for mkv). Does the demuxing behaviour hit you? It could be changed but this is isn't completely trivial: For 3D files, the SAR is 2/1 (or 1/2) by default, so in this case, the demuxer would still have to output a sar although not specified in the file.
