CIL | Yes, given time. There was a report out not long ago talking about how the genetic resistance in waterhemp to glyphosate is actually temporary and if everyone would stop using it, then it could become susceptible to it again. However, the problem is similar to how you got waterhemp in the first place....alot depends on your neighbors too. They keep using roundup and their waterhemp keep bleeding over into your fields. Heck some of our worst trouble spots here are under power lines because birds eat the seed several miles away, land on the power line and crap it out. So even though we do our best to rotate several modes of action, one bird can literally crap on our hard work.
We're all in the same boat, just have to do our best to manage our little corner of it. You are right to be worried about over abusing roundup...or any herbicide for that matter. Which is why it's also important to tank mix several modes to attack hemp in each application (pre or post). Just relying on a PPO like fomesafen in a single pass means you'll be helping select waterhemp that are developing PPO resistance. It cuts both ways. Not trying to be a naysayer for what you are doing, just some food for thought.
fyi....here's the report
