Is that required?

Could the suit itself be used as a type of airlock, to leave outside things outside?

For example, mounting yourself onto a wall, then the back/whatever of the suit opens to the inside, and you hop out? (yes, there would be some dust recovery required, but minimal in comparison)

The challenge with the "suits stay outside" model is that you basically need some kind of airlock between the suit hatch and the ship hatch. You might imagine both hatches get contaminated when the suit is detached. Then when you dock, that whole between-hatch space needs to be decontaminated before you can open the two hatches, because the outside of the suit hatch brought that stuff into the airlock.

edit: in that context^ search for "SEV suitport design" find NASA has written some docs on the matter, eg https://ntrs.nasa.gov/api/citations/20130013652/downloads/20...

Isn't there a plan for the Artemis lunar rover to be configured this way? The outside of the suit never comes inside the rover.
