So what's the problem with adopting a standard approach that ends in a successful on-field landing in the event of the engine stopping?
A glide approach isnt a standard approach, a powered approach is a standard approach, thats why by far the majority of schools teach powered approaches as standard.
Do you carry a parachute? Probably not because you realise the risk of having an incident where a parachute would save you are minimal-now apply the same logic to a glide approach and you will come up with the answer.
As a matter of interst if the engine stopped for a real during a glide approach that would put you below your idle power glide angle - have you ever considered that?
