At first thought it does seem logical to assume the cap would throw the intonation out. However, it's better to think of it as an extra finger playing a barre: if notes at the first fret are intonated correctly when you fret them, they will be intonated correctly when the capo is fretting for you. The compensated nut or Feiten system works mostly by fiddling with the scale length to ensure that the same fret positions
Did you hear that? That was a penny dropping. What you're saying makes sense (I think), because the compensated nut will adjust the scale length for each string and the "compensation" will be spread along the string when the instrument is tuned.
As for complexity... I think that too much is usually too much. I note that big outfits who have lots of roadies can have more variables, but they use the roadies to control the variables. An example would be Andy Summers who needs to use a lot of effects and has a roady patching his stomp boxes for each song and even turning them on and off.
But sometimes I think it's a bit academic. Can the audience really tell the difference in tone between Keef's '71 Tele and the '72? Do they really hear the adjustments that Andy Summers's roady makes to the flanger for each song? In 2007 I got to see Richard Thompson playing electric with his band, and I was surprised at how little he manipulated his gear during the show. As regards effects he seemed to have a couple of pedals that were just turned on or off (no twitching of dials, and where I was standing I could see his pedal board so I'm sure of this), and he didn't even seem to change pickup selections much - left it on "bridge and middle" most of the time. He has a very professional team around him, but not a big team - so he can't dedicate somebody to remotely controlling his stomp boxes via a PC.
