I think the goal with the expertise feat taxes was to make it so the extra benefit was the attractive part. So you take your feat tax and something a bit extra onto it, which usually is worth a feat (usually, not always). It makes them more palatable to me, even if I think it's the more silly of the possible solutions when you have themes in the game.
I can't emphasize enough how much I wish themes were introduced earlier into 4E and accounted for things like expertise at the time. It could have been such an elegant and brilliant solution.
