To be fair, I guess Infocom games like Hitchhiker's didn't count SCORE and HELP as a turn... but they DID count INVENTORY as one.
Is there an option to set INVENTORY to tick? Or will there be. I guess if I really want it to count as a turn in future (which sometimes I do... in turn-limited situations) then I can manually code an INVENTORY response, that will make it count as a turn.
