The CAA actually produce a very interesting document on this topic (
Safety Sense Leaflet 07: Aeroplane Performance).
It's daft to try to relate single engine/unclassified aircraft performance to commercial operations. In the public transport multi-engine world, there is always a stop/continue decision to be made (and most company's have SOP's dictating when a stop is
always required). In the SE GA world, it's more grey but with a single engine, much of the choice is taken away from you. I know I'd prefer to slide through a hedge at the end of the runway in deceleration than decide that I must continue with some kind of problem with the airworthiness of the plane and run the risk of a later accident from height, at greater speed or under high power settings as I tried to get airborne.
