"git clean" without -n/f errors out, hinting the availablilty of -n
while mentioning -f; that is the safety, isn't it?  Once the user
decides to give -f, the user _wants_ to remove cruft, and it is a
hinderance to require any further confirmation.

Your problem description sounds like that you want to drive without
wearing seatbelts but in case you get in a collision, you suggest to
make the seat automatically stick to the back of anybody who sits on
it with superglue to make it safer.

That approach might give it an alternative safety, but it would make
it extremely annoying if you apply it also to people who do wear
belts, no?

This extra confirmation should never be the default.
