That's _almost_ what I'm looking for, but not quite. I'm specifically interested in the case where a single Camera creates two FBOs to support multisampling, and I want a depth buffer in one FBO but not the other. (See my original post for more detail.) Currently, I always get a depth buffer in both FBOs which is not what I want.
With your change, if I attach depth to the Camera, then I also get a depth buffer in both FBOs, and if I don't attach a depth buffer to the Camera, then I don't get a depth buffer in either FBO, which is also not what I want. So your solution, as currently coded, won't help with my situation.
However, it's good to know that there are others besides myself who have concerns about the efficiency of the present FBO implementation.
