Although no new thunderbolt hardware is being attached the cable snake spinner is shown periodically. The root cause seems to be a kernel change where new are generated for the ethernet device inside e.g. a TB16 dock, which leads to probing property changes, which in turn lead to the cable snake spinner being active.
