Of course there's two sides to this.
On one hand, this could discourage more relaxed warden..ing.. and people could in turn be really strict about this. Also it closes a loophole that REDs can use which can be seen as both good because it enforces less chaotic rounds and less "bullshit" but it can also be seen as fun-killing for prisoners which is bad, but that's debatable.
However, on the other side, from what I've seen a lot of people don't refer to/care about detours & delays that much anyway. I haven't seen much people use it as a loophole on RED and on BLU I haven't seen much wardens incorporate no detours or delays into their orders either. I feel most people play the game as if it's already a thing and that logically you should just follow the warden's orders without any detours or delays, but perhaps use of this term is more prominent on servers such as IL Jailbreak which I feel has a more informed playerbase (in regards to the JB rules). But anyway, therefore I think this would just make things simpler and wouldn't have a big negative impact on the already existing ways people play Jailbreak. Of course however that's only for the most part because it's not like nobody uses this term.
Anyway, I don't have much of a solid opinion on this, so I suppose I'm neutral for now.
