This is basically how it was, and I think there were benefits that some may not have registered ("you don't realize what you got till it's gone" scenario).

A very good question.
International departures is segregated from domestic departures because of duty free sales. If domestic and international are combined, the duty free proprietor must deliver the goods to your aircraft door. If the whole concourse is international only, the duty free operator can give you the goods like any other establishment. On the odd chance that your international flight gets cancelled after you make duty free purchase, the traveler must see CBSA and potentially pay duty and other taxes on their purchase. In most cases unless CBSA sees a pattern of cancelled flights, pac are sent on their way without further charge.
Putting international and transborder operations in the middle of the terminal complex makes sense until the central processor facilities (checkin, security, pre-clearance, CBSA) need expansion. it is very time consuming to build an new domestic terminal area and then renovate the old terminal to expand the international operations.
