I have been shown the prop-stopped handling of a piston single. Thought it an experience but wouldn't teach it to my PPL students.
Definitely agree with the sentiments about insurance.
Don't think it's safe to even do it in favourable circumstances, ie at a reasonable height in the overhead of a suitable airfield on a 5kt-straight-down-the-runway sort of day, because you're leaving a big hostage to fortune (will it or won't it start) and you can bet that if your luck's out in the engine dept, it's bound to be out in other ways too.
