I’m confused. D&D 5e combat is 100% built on the idea of panning around the room, or at least it seems so to me. It’s broken up to to six second segments and everyone is involved.
Does it make sense to you that it’s important to establish what other characters are doing while one PC scouts ahead or while a trap is being disarmed? How can the DM adjudicate the effects of a trap going off or of a wandering encounter during a scouting mission without that information?
No it isn't. You never pan around the room while someone is taking their turn in combat. It's the only time when a player can be absolutely guaranteed to have the spotlight to themselves while they announce, perform and complete their action.
In exploration, the player announces their action, begins to undertake that action, then the camera swings around to everyone else for however long in real time it takes to resolve their actions, then, finally, once everyone else has had a go, that first player gets to finish their action.
Note, that while the camera is panning around during exploration, that first character must not participate in any other actions because that character is doing that first task. Meanwhile, the rest of the party can have a conversation, do this or that, interact with each other or possibly NPC's, interact with the environment, either singly or in groups. IOW, by pulling the camera off of the exploring character, you sideline that player for the duration of that action.
Again, this is why players find exploration so lacking. If every time I go to undertake a 10 minute task, the table then spends ten or fifteen minutes doing whatever that must not include me (since I'm undertaking a task), what incentive is there for me to ever undertake that task?
Thinking about it, this is pretty much the Dekker problem from Cyberpunk. The Decker goes off to do his hacking and then the game either focuses entirely on that character for however long, sidelining the rest of the group, or you sideline the Decker. It's not an easy thing to resolve.
