Other than Pakistan, there are other communities too which are active on their local threads like "Укpaїнcькa (Ukrainian)" and "বাংলা (Bengali)" and they are also waiting for their local board.
Yes, I think all those local threads that you mentioned should be considered when during creation of new local boards. I also agree that there are some boards with very less activity but as they have been on forum for sometime so I believe they should also remain on the forum.
Ultimately, it's Theymos's decision because only he knows better that when new boards should be created. I hope Pakistan and all those mentioned communities may get their local boards in 2024 as a gift when Bitcoin crosses its ATH.
