That necessary features have a detrimental effect on an optional play-style is both predictable and unfortunate - however it's not likely to change Frontier's stance. The furthest that Sandro seemed to be prepared to move on the delayed menu exit "issue" was to increase the delay, maybe, no promises, no guarantees - not stop players leaving the game.
I'd have no problem with an increased timer, but put the confirmation at the start in case real life comes calling.
