No, but the fact that they added the Oplot-T and Oplot-M should be a sign to you that the “rule” you quoted doesn’t apply when the main operator/exporter nation isn’t a tree in the game.
Also both Fokkers are different models but yeah Finnish was added like 2 years before Benelux was and it was their only unique TT aircraft of which now they have nothing as gaijin refuses to add their uniquely modified vehicles like the Mig 21 MGBT
Technically its not copy and paste yet, i could see gaijin adding it to multiple nations to get money from. Sweden air has been so poorly handled theres a reason no one plays it compared to something like Isreal lol. Gotta squeeze money out of the only source of income some nations bring so get ready for Trialed K2’s for everyone lol.
