The problem is most people who hit those TL;DR categories would be far worse than what you experience on any other form of content. You can argue that it will add to the enjoyment as much as you like but if not enough people queue for it then it would be dead on arrival. These things are all underlying issues as to why it wouldn't really be commonplace to clear the duty within the same lockout so realistically it's just an exercise in wasting time.
To put it into perspective. What do you do when you get a duty wherein you don't fully understand the mechanics and cannot, therefore, clear the fight without first going through what would essentially be a learning party? Second of all, what do you then do when other members of the group are in a similar position or simply lack the DPS output? Going to bash your head against a wall for 60 minutes?
A vast majority of people do a roulette with the reward being a core focal point of it, what is going to be the reward for potentially wasting an entire lockout? Just to really TL;DR even those willing to do the content may more frequently be in a position where they spend the entire 60-minute lockout making really no progress whatsoever to a reward. Traditional roulettes are a different matter entirely. If you don't like it then don't queue for it, that is a commonality between the two, but even those that want to queue for it will still have the additional caveat of spending significant time making no real progress toward a goal.
Regardless of your own personal feelings of enjoyment, a majority of people are goal driven. So I just posit the question to you; what's the reward that I gain for doing the roulette in the first place? What's going to be the reward that prevents the roulette from being dead on arrival?
Again, amazing on paper but poor on execution especially when you cannot guarantee the competence or ability of other people in the group.
See the difference between Eureka, Bozja and even mount farming is that you can almost guarantee you will make progress within the given time frame. If you spend an entire lockout (aka 60 minutes of your time) just chain pulling an extreme primal, then you make absolutely no progress to whatever to any goal. Bar the prospect of fun, something which you equally gain by joining KFF parties, kill parties, or learning/practice parties.
