Not if people start sprinkling assume() all over the place. It
becomes one more thing to check, and because implementations differ,
you'll have to check your particular compiler's implementation and
whether it changes behavior when it encounters that particular
assume()ption.
I really can't think of a more mischievous coding practice.
