Sorry i should say front yes rear no.
I have a MY12 D4 with e-diff and been to quite a few interesting places off road.
From my experience, can't say I've ever felt the need for this type of mod.
Each to their own though. My vote, for my use, would be "no need"
As soon as my front diff needs rebuilding a locker is going in. Yes many times I wish I had one.
Ive seen both Gordon and Richard K doing some pretty extreme stuff in their D3s with ease,cant see the point of lockers and their interference with factory systems,especially in the D4 with improved electronics.Good money to spend eleswhere,like 18" rims.

Like Rich, when my front diff needs attention I will get a front locker.
Might never use it in anger, actually hope I never have to, but when your truly stuck and bad **** is about to happen it's nearly always a front locker that gets you out of the sticky bind.
I don't think a diff locker would have any detrimental effect on traction control. It will make life easier for it as it will not need to engage at all when it is locked (for the axle that is locked). Less issues with hot brakes, less brake wear,more steady forward progress without TC having to take that split second to work out what it needs to do.
disadvantage is the stress on the drive train when not driving straight - usually not too much of a problem in low traction situations.
Regarding the infinitely variable diff, that only relates to the ediff. If you have that then you are ahead of those that don't as traction control is always "braking" the vehicle. If LR put an ediff in the front and back then you would have the perfect setup.
