@Ghost there are definitely issues between staff and players, and players and players about what the expectations are.
The topic was piqued for me over, as I mentioned, examples of play where the players were intent on sharing more internal state information than I usually see in MU* RP. To me, it fits the "newer" ideas category like game setups where the players are filling out the world, or actively creating their own IC situations and difficulties like a mix of a character-actor and show writer. There is more info put out, so people can get in on whatever, but also that's just the goal to create something like the experience of watching of a show for the players.
Given how hard that is at an established gaming table, it's unlikely to ever be seen in MU* RP.
Just food for thought on RP creation.
