Two questions
Do Enhanced MAIs lack the social skill and warden ability, or is it only the standard MAI that lacks them?
What gun is that on the automated weapon base in the image showing the MAI production chain and weapon bases? (and where does one find it?)
Both MAIs don't have any social skills. They are robots, why should they care about social stuff? 
*gets nervous twitch*
Why would a robot care or have social skills?
(wall of text/rant inbound)
Commander Data from Star Trek comes to mind.
A few holodeck characters from Star Trek have seemingly gained sentience and the ability to care (at least to care about their own existence)
Then there is HK-47 from Star Wars Knights of the Old Republic (he needs someone to call "meat bag" after all, and he would be good at the job despite the fact he would rather shoot someone than talk to them, but he's good at following orders to not shoot people... usually. I think someone gave him Protocol Droid stuff, since he is a disgruntled translator at times...)
Protocol Droids from Star Wars. Built specifically to communicate with humans (usually as translators)
Dot Matrix from Spaceballs.
Chip from the movie Not Quite Human at least gets close enough to appear to care.
At least one gynoid from Ghost in the Shell pole vaults out of the Uncanny Valley (one that restrains 'her' owner/master without warning, before he was able to do something that would have got him shot, rather than helping him to escape)
Also, the Tachicomas (spelling?) from Ghost in the Shell. (They are robots that care AND that can pack enough firepower to make a Centipede wet itself and can outrun a Scyther and rip off Spiderman to boot, mixed in with child like innocence/curiosity.)
Naomi Armitage from Armitage The Third/Dual Matrix knows one that cares. (other than the one that becomes a plot advancement device early on)
Lots of Androids/Gynoids from both the above settings are capable of caring for and communicating with people, and even used as companions, even though they are just complex robots, then can 'appear' to care, simply by being programmed to. (that said, since one of the MAI research things is 'caring' for people, it should include psychologically and not just physically, that is being able to talk even if not capable of having any sort of emotional or social reason to do so other than to support the mental well being of others)
Casts/Caseals from Phantasy Star Onine. (kind of of an example...)
Technically the Bioroids from Appleseed. (some care about humans)
Sonny from the movie I, Robot.
WALL-E and EVE from the movie WALL-E. (By the looks of MAI, you already know who EVE is...)
That robot gal from Metropolis comes to mind. (the old B&W Silent Movie version was well worth watching... sort of undecided on the anime adaptation...)
Such robots probably also exist in every other movie/anime/cartoon/comic/manga with sci-fi themes.
Any robot/AI that could pass the Turing Test could achieve such things simply through extreme complexity, even if they didn't 'care' about anything in the first place.
So, lots and lots and LOTS of reasons why robots could care, or otherwise appear to care, even if they were still heartless, soulless, emotionless machines that couldn't 'care' about anything in the first place, beyond the simple act of emulating the appearance of caring.
That said, I would think that the Enhanced MAI would have social skills, seeing they need an AI Persona Core thing.
Even if it does not get added to the mod, could you at least tell those of us with basic modding skills, who want MAIs to care, what we need to tweak to give an Enhanced MAI the ability to be social and even handle the Warden task?
Random crazy idea... giving a colonist a 'cyber-brain'/'brain case' like Ghost in the Shell, and plugging 'that' into an MAI in place of an AI Persona Core thing... (to heck with adding stuff to the body, add the brain to another body... Like Full Prosthetic Bodies from Ghost in the Shell.)
