Thank you Karel, at least the list now has an answer on how to find the mounted subvolume. For a moment I thought that no one had noticed this part of the question. In any production scenario, the first time you try to explore btrfs subvolume capabilities it becomes obvious that this feature is missing and it is weird how this has overlooked for such a long time.
