I think it is useful to allow path testing even when the current
path is working, and the protocol should support doing this
without disrupting ongoing communication (which does not seem
to be possible in your proposal).
(E.g., suppose we have two interfaces, one very fast and cheap,
second one very slow and expensive. If the first one has a temporary
problem, and we switch to the second one, we want to switch back
when possible even if the second interface keeps on working forever.)
