I think that's the best practice, also for avoiding condensation, but isn't it pretty uncommon at least for residential builds in the US? Here in Washington, codes were recently changed to require continuous insulation, but I believe that's only with the prescriptive method. From what I've seen most builders seem to continue working around it and doing cavity insulation only.

Depends on where you live, but that seems to be fairly common anyway in new builds.
