In the past I've worked with devs who complain about the cost of context switching when they're asked to work on more than one thing in a sprint. I have no idea how they'd cope with a tool like this. They'd probably complain a lot and just not bother using it.

I think that paradigm is shifting a bit with agents where there are more downtime waiting for things to run. It's definitely not for everyone and the switching cost is real. We're trying to make that better with better UX / auto-summary, etc.
