So, here's a list of debatable items. Please correct me if I'm wrong. Discussion can start. ;)
***UPGRADES***
Wave Beam (obviously)
Spider Ball (no escape I guess, unless you can Infinite Boost back into oob in Quarantine Monitor)
Super Missile (might be possible but if it is it's likely very hard, afaik nobody has ever done it and escaped Phendrana's Pirate Labs afterwards)
Thermal Visor (no escape I guess)
Gravity Suit (no escape I guess)
Wavebuster (no escape I guess)
Flamethrower (might be possible if we can scan the post from oob? Wave Troopers can't be defeated without Wave Beam (as far as we know; I mean Flamethrower deals damage to Metroid Prime when MP is on Power Beam vulnerability mode lol)
***ENERGY TANKS***
Magmoor Workstation ET (still not sure how you could escape afterwards (after getting into the Magmoor Workstation SW, infinite boosting into the little sub-room and getting the ET)
Research Lab Aether ET (no escape I guess)
***POWER BOMB EXPANSIONS***
Security Cave PBE (should be possible since Storage Cave SW is a thing now (and with Grapple Beam, it's possible to get oob in Phendrana's Edge, too)
***ARTIFACTS***
LIFEGIVER (no escape I guess)
ELDER (if it's possible it's so madly difficult with all the wallcrawling required that I wouldn't want to do it anyway)
SPIRIT (should be possible but escaping means you have to go back oob in Phendrana's Edge or Storage Cavern)
***MISSILE EXPANSIONS***
Biohazard Containment ME (no escape I guess)
Training Chamber Access ME (no escape I guess)
Phendrana Shorelines (upper) ME (how, T3, how?)
Research Lab Hydra ME (no escape I guess)
Research Lab Aether ME (no escape I guess)
Gravity Chamber ME (no escape I guess)
Quarantine Monitor ME (no escape afterwards unless you can Infinite Boost back into oob)
Main Quarry ME (Wave Beam needed for the crane to blow up the wall and thus setting the ME free; I don't think it's possible to get that ME from oob (without getting permanently stuck))
