FWIW, my .screenrc is 4 lines. My .tmuxrc is 26 lines, and all it tries to do is get a behavior comprable to screen. Ie, using the same ctrl-a,
supporting ctrl-ac without needing to release ctrl before the second character, allowing titles to pass thru tmux to the title bar, etc.

So, veering from the tmux defaults to change them to the screen defaults takes more work in tmux than in screen? Go figure! I never would have guessed. (Hint: It's easier in screen because they are the defaults)
I've never used tmux and I find your post to be biased towards screen. tmux isn't being touted as a 'drop-in replacement' for screen, but that seems to be how you are evaluating it.
The answer to you is no, I think it is. It's a question at least, it's not it it _is_ a killer. That I think is misleading. At least with this title you still have to come to your own conclusion.
I agree that the answer to that question is almost always "no". But I think this case is a rare exception where the answer is "yes", or at least "probably".
