I buy it from a couple if perspectives. Stage Manager with an external display still needs a lot more work, like 1 year of driver work to cover all the idiosyncrasies of various external monitors, and 3rd party apps need more time to update to size classes, and have it work on external monitors.
I think Apple will be making good progress if Stage Manager is solid on LG UltraFine monitors in landscape. Once you start branching out to HDMI, USBC, ultrawide, and monitor orientations, things are going to get wacky. It will take a long time for apps to be updated and for Apple to get drivers working well. They also have a lot work to support TB3/4 and USBC docks.
