What side is vacuum only matters structurally. The seals on hatches, space gloves, windows, any joint between materials, they all need to handle 10^-12 torr vacuum.
I disagree. The reason the seals matter in a vacuum chamber is because you have to create the vacuum, which is very hard to do. If the vacuum already exists (in some area of space) all you have to do is seal against 1 atm of pressure escaping. You seem to be under the impression that high vacuum is somehow the inverse of high pressure. It's not. It's just absence of pressure, so you only need to seal against the amount of pressure your vessel needs to hold.
It should be obvious that a suit or craft that can maintain 1 atm pressure in a 10^-6 Torr vacuum can also maintain 1 atm pressure in 10^-12 Torr vacuum. There is no practical difference at that level when your goal is to maintain pressure.
I would say I have a basic understanding of outgassing, but that would be more of a problem if your concern is trying to create or maintain a high vacuum. It's not a problem if you just need to maintain pressure. Pressure and vacuum are not the inverse of each other. Vacuum is merely the absence of pressure.

You don't understand the concept of out gassing.
