This is a duplicate of the thread here: Updating the default startapp template, as @czue already linked back to.
It’s much better to keep related conversations in one place, rather than re-raising the same topic in a new thread.
As far as I can see there’s no immediate consensus around a change here. I agree with @cory, the best way forward is the WIP DEP, which has more/better template support in its likely scope.
