If I'm hiring super creative or deep planning or design roles i want "bursty" people who can do super intense periods, more common lower intensity cycles and then recharge for a planned period of time.

If the workload dictates requirements I'd love to find anyone who wanted a constant queue of variable days but I've never met them aside from contractors who want a minimum and will bill extra, but they still seem term-based and want vacation.

At a managerial level i can plan around predictable days off, but not variable days when i need to coordinate more than a few people.
