Okay, dropping the funny act now. What do we know of this room for real?
- Does it only have access via outside and Jeffries tube? Never established - we only see two walls out of presumable four.
- Is it a big room or a small room? Behind Picard in the one reverse view we get, when they grapple for the gun, there's a diagonal bracing that may or may not indicate a slanted back wall. In stage reality, there of course was no wall there.
- Is it a room for stargazing? It's exceptionally ugly, with said bracings and so forth, so highly unlikely to be a recreational space. Might be a vitally important observation post, though.
- Is the hole into space for moving stuff through it? Might well be - the lower edge is close to the floor, so anything brought in could be smoothly delivered to the floor.
- Is it a hole for walking through? This ought to be fairly easy, but one would have to stoop a little, even if gravity at the junction of the hole and a putative tube attached to it were to "bend" at the threshold. Why build the hole to be those crucial couple of dozen centimeters too small?
- Is it an airlock? No big reason why it wouldn't be. But again a very awkwardly shaped hole for that. And a spacewalker stepping outside would have to be an acrobat to get his boots to the outer hull.
- There's a big console by which Picard operates the hatch, supposedly controlling complex things. We see no complex things. But anything could lie behind Picard's back, such as honking big tractor beam cranes, or probe launchers, or whatnot. Why these doodads aren't permanently against the hatch could be for two reasons (the third of course being "there is no doodad there") :
1) The user can select from multiple doodads to be placed against the hatch.
2) The doodad brings stuff aboard, so a clear space is left for the stuff to be brought aboard.
Compare this to the only other shuttered porthole ever seen in Trek, the one from "Mark of Gideon". The controls there were much simpler, and we saw there was nothing in the room that could be brought to peek through the porthole.
