Controlled residential ventilation, exhaust air, pantry with sliding door

Hello!

Do you think it is necessary to plan an exhaust duct in the pantry or not? The room (3 sqm) has a small window, and a sliding door will be installed between the kitchen and the pantry. According to the current plan, the kitchen will have two exhaust vents.

Partly, it is about whether I could install a smaller distribution box if I do not provide the exhaust vent in the pantry. The smaller distribution box could be installed more space-saving in the technical/laundry room.

Every room that is not connected must be ventilated otherwise. You can of course do that. I just find it pointless to try to save a single valve on such an expensive, central system. It might even make sense to simply reassign one from the kitchen to there.
