I wonder whether parsing a text based output is really the most elegant method here. How about a libbtrfs so that other tools can benefit from btrfs tools functionality? This was also desktop environments wishing to make use of snapshot functionality or advanced disk usage reporting for example can easily make use of it without calling external commands. Of course it would likely me more effort than to implement structured output.
