Yeah the fact you can't craft in this area almost doesn't make any sense, unless you accumulate a rested EXP bonus just by being in the room. If that's the case then it probably does make sense not to allow crafting as you could easily sit there and get an endless EXP bonus. They intend it to be something you get for using these rooms, not really for spending all your time crafting in there. Also I figure it might even decrease the rate of interaction between players if that were the case. Less people sitting in an area crafting, more hiding in their private rooms for the EXP bonus.
