I think if it became SOP then you've negated the reason for doing it in the first place - namely bringback, aka recovery weight. If you plan to do it on a routine basis, you'd have to be a dribbling idiot not to include a fuel margin for a very short go-around, even if that go-around included hitting the emergency ditch everything button (which come to think of it won't be easy with internal weapons carriage). Additional fuel margin = additional recovery weight, which reduces your bring-back etc....
The more you scratch, the less sensible it looks.
