I'm pretty sure that downtime and training have been a part of D&D in one form or another since 1E. We've used them to some capacity in the past. Nowadays we play for maybe 3 hours once a week and communication between sessions regarding the game is minimal at best. Since our games are more adventure based with not too much heavy roleplaying, it's not something I've considered worth incorporating. I like your idea and of separating sessions by adventuring and roleplaying & downtime. I may look into the 5E versions of this and give it a try. It may add something that's missing to our game.The downtime rules are actually in the DMG (and expanded in XGtE - not sure about TCoE). However, it was just the concept that inspired us to make it a bigger part of our game, we took the idea and made our own guide. We basically have adventure mode and downtime mode now when we play. We always have a downtime session at level up because we require training, research, etc. to level up. However, we cover lots of other things during downtime too. It basically shorthand for roleplay session. We can also throw in "downtime" activities at other times too.
