I may be reading into this too much but it feels like Aegis are trying to ward off foolhardy individuals that would dare to try enter the intact pieces of Titan remnants on foot.
Too bad we can’t actually do that in the game. I would also like to not be concerned with vacuum hoppers crawling over the hull and trying to get inside.
I have theorycrafted a few space suit loadouts for just such occasions (and theoretical monster hunting on theoretical planets with theoretical animal life

). Artemis with improved jetpack for the best zero-g maneuverability, damage resistance, ammo capacity because there ain't going to be ammo crates just lying about, plus it has huge battery capacity from the factory with 3 charge packs for impressive endurance. Haven't decided whether to have night vision or improved shield for the fourth mod—on one hand, Titan wreckage interiors are undoubtedly going to be dark, but on the other hand, shield is the first line of defence for not only combat, but it also protects from falls and other violent impacts and, curiously, from the caustic "aura" of Thargoid artifacts. Silenced Tormentor for sidearm, Intimidator or C-44 for main weapon (depending on what resistances the theoretical on-foot thargs have).
On the other hand, one may think that Maverick may be necessary to cut stuff open inside the wreckage, but judging from spire sites zapping certain biomechanical structures with the energy tool will be all that is needed. And I'm sure prof. Palin can come up with a way to weaponize the genetic sampler somehow
What is certain is that the Dominator suit lacks any tools, jetpack and endurance to be considered for such incursions. Which makes the whole ordeal truly crazy—you're diving head-first into the most hostile environment for humans potentially containing the most dangerous adversaries in the known galaxy, and you need to pick a spacesuit that is the least suited for combat
On a side note, Artemis also has the best olive drab cosmetics. Spectre Gray base suit with Quest Green bits and bobs looks straight out of Forever War
