It gets a little more complex when you want to make stems for TV or at least vocal and instrumental. To “cover your ass” as it moves to mastering. For organizational reasons and also for reverb return reasons. Requiring vocal and instrumental stems at the same time as the mix (without requiring another pass) means that you have to use different reverbs for vocal and instrumentals. And the routing and organization gets more complex. But in my not so humble opinion, this is a big advantage in the long run. You capture your mixes and stems in the session and if there are revisions or tweaks you can punch in and out and replace sections. It saves lots of time in the long run.
