True. I was hesitant about that part myself.
But think about it this way -

One of the reasons is that when developers change
some code in the vicinity of freeze they want to run a fast
smoke test with tests the exercise freeze.
In this perspective, it seems useful that the freeze smoke test
will also exercise freeze when used as a trigger for internal
xfs tasks.

That was my thinking, but I have no strong feelings
either way, so if others don't like it, I can drop this part.
