I think you have the right idea in your "update". Treat Drive as flat, make calls to list everything, and generate your own tree from that.

   • the second (recursive) over the parents id of each element,

rejecting all the elements that not contain the id of my specific folder in its parents id list.
Don't worry, it's just one Google APIs call. The rest of the job is local.
