I dont know if this is where I would go to suggest features. But I have a Galaxy Watch 3 and maybe it could be implemented for other watches.
In the settings you should be able to change the way the watch is oriented, ie 90°, 180°, 270° and 360°. Not talking about an automatic detection like when the watch is charging, but a setting that has those 4 options.
People that wear their watch differently or on the off hand arm should have the ability to pick where the home and back buttons are located while still having the watch face down.
