The only potential downside I can see is if you're real concerned about the start date/time of a task assiged to a team.
If a worker goes into the Team Requests and claims several tasks they know they can get done today - they will all have a start TIME of whenever that worker claimed the tasks, not necessarily the time they actually stared working on each task.
If they are only claiming one task at a time and working on that, I see no downside and the automation of not needing to do two separate steps is a time saver.
We've made the switch and having that "Actual Start Time" when the tasks status changes without someone needed to do that extra step is going to be great for reporting moving forward.
