I think the hype around needing to cast a whole fly line is a red herring. It just causes people to buy super fast fly rods instead of more versatile rods that are fishable at normal trout fishing distances and do things like roll cast, cast 10', protect tippets, etc.
Even wading a large river like the Yakima (not in a boat where you have mobility to get close to a target), I cast 20'-50' the vast majority of the time. However, nearly every time I fish the Yakima or similarly large rivers, I also need to cast 60'-70' occasionally to reach a distant spot. That's still doable with medium and medium-fast action rods if you're a halfway competent caster.
I rarely try to fish past 70'. Even though (in ideal conditions) I can usually throw a line 90' with a 9' 5wt or 6wt rod, my ability to be accurate, control a drift, or set a hook at that distance is poor, so I tend to not even try.
