I noticed something in this too:

Is there a mechanism if BFCP for the holder of the floor to yield it to
a particular participant? That seems to be required for the last point.
If the focus simply relinquishes the floor, in the expectation that the
transfer target will take it, there is a window when someone else might
grab it.
