yes, I'm not sure the logistics but it's definitely done in other places. Certainly in Australia if you are travelling international you go through outbound immigration control. I'm not sure what happens if you need to get out again for some reason after you "exit" the country. I assume you have to "re-enter" the country by circling through inbound immigration. Perhaps having no land borders makes outbound immigration control more reasonable. It does seem like the cost of adding some secure departure lounges might be less than circling huge numbers of passengers through unnecessary immigration procedures, security lines, etc
