I believe they put desiccant in the separator channels. The air that is
sealed in does not have to be absolutely dry.

Otherwise I agree with your comments.


The air in the window will equalize with the outside air. The hole could
be sealed when the dew point of the outside air is sufficiently low
(below the lowest temperature in winter).
