And there's the issue of keeping moondust out of the lungs of
astronauts. When they go back inside after spending all day digging
around the outpost on the Moon, and come back in all dirty. Then the
dust falling off the suits as the astronauts undress once under air
pressure. It'd be a bit like breathing that dust and grit (containing
micro shards of window glass and gypsum sheetrock just after 911 at
Ground Zero in NYC).

They're quite concerned about that also.
Maybe they can use some sort of high pressure air hose to blow the dust
off the suits and recycle the air from the airlock back through a filter
and into the hose again,, until all the dust is trapped in the filter
rather than on the suits or interior of the airlock.
It would take two astronauts to do it right, but I assume just like in
skindiving they'd use a buddy system for EVAs rather than going outside
solo.
Electrostaticly charging the filter would also let the dust stick to it
better and speed things up.
