I mentored an FTC team that was using the vision system this year, and my overall impression was that the TensorFlow model was absolute garbage and probably performed worse than a simple "identify blobs by color" algorithm would have.

The vision model was tolerably decent at tracking incremental updates to object positioning, but for some reason would take 2+ seconds to notice that a valid object was now in view (which is quite a lot, in the context of a 30s autonomous period), and frequently identified the back walls of the game field as giant cubes.
