Why do you want it to windmill? there is no vacuum system.

Quicker restart.

In the only situation that I can think of in which a quick engine restart
may matter, you really wouldn't want to dive for windmill. Besides, using
the starter yields the desired result at least as quickly.

You don't need to dive on a direct drive, the engine continues to windmill
from the time it stalls. In Cessna's you have to slow to very near stall
speed to actually stop the prop. I would suspect the same for all the
Lycoming and Continental powered aircraft.
