Perhaps not unserviceable in theory, but probably unserviceable in practice. It's a whole lot more expensive and risky getting humans to L2 and back, than low earth orbit and back. (After all, you are going past the moon and then some)
A one way robot mission would of course be cheaper, if it wasn't for the fact that we are several decades from building a repair robot that's reliable enough not to need repair on it's own.
Servicing a satellite in L2 is probably only practically possible when we have a space station in L1. Both because the energy cost will be much lower, and since that would mean that our space-technology is much more mature than today.
... and of course I mix up the lagrange points of the Sun-Earth system with the points of Earth-Moon.
The point still holds though.
