Wouldn't it > make sense to treat missings as zeros in this context? I see your point, but my inclination here would be to revise the behavior of "Add observations range dummy". I think this should be exempt from the usual rule that we write values for newly generated series only within the current sample range -- otherwise this dummy becomes kinda useless. We should write zeros for observations outside of the current sample, not NAs. Anyone see a reason why not?
