I think your distaste for Maya might be coloring your memory a bit. Maya was teary by the end of the scene in Gender Studies, but at no point was she presented as angry.
Likewise, would it be fair to point out that Sage will only let the MC stay in her dorm if he gives her sexual favors? Whereas Maya, despite only promising Derek to let the MC stay only a night, will allow him to stay indefinitely even if he has negative RP with her.
Your overall take on Maya is justifiable even if I disagree, but I do think you are a little too eager to apply it in situations where it's a questionable fit. It weakens your argument unnecessarily.
I'd say the MC has strong but uncertain feelings for all the main girls - until and unless he turns them down. If he turns them down, he seems pretty uninterested in them romantically. For example, the Episode 7 wrap up screen has the MC think it sucks if Jill has to accept Tybalt's demands when he isn't interested in her romantically. Likewise if he never visits Bella in the library in Episode 3, he never comments on the tension between them and there's no awkward pause when the MC says he'll be taking her class. (The only exception to this is Josy if you tell Derek you still have feelings for her.)
If the MC is pursuing them, it's a lot more ambiguous. Jill seems to be the most defined, at least if the MC goes on the date with her in Episode 6; he thinks he's falling for her. Sage is probably the runner up; as bad as the Rebound Guy speech is, it does establish that he has legitimate feelings for her and doesn't want them to become mere friendship.
In theory he felt something similar for Maya and Josy in Episode 4, but it's a bit undercut by the MC immediately asking to sleep around in Episode 5 and rarely thinking about the two (in an emotional sense) after that.
Bella... is unclear. There's obviously meant to be a lot of sexual tension between them (though it falls very flat for me), but unlike Bella, the MC doesn't really act like it's more than carnal until Episode 8. Even then, the first date seems to be as much about obligation as it is about romance. IMHO, anyway.
Of course the Crossroads completely rewrites all that. The MC's affection for all the girls is suddenly so intense it is awkward seeing Maya, Josy, Jill and Bella together, regardless of how dead the spark between them was. This persists just long enough to ask a bunch of awkward questions at breakfast the next morning, at which point he'll search his heart and reload his old feelings. It's then up to us to break any ties and drop the unchosen LIs into the "no romantic feelings" bin.
Of course, even when we pick a LI to romance for real, the MC still seems to be pretty tentative about it. So I'd say the MC's feelings about the LIs in Season 3 will be deep affection if he's on her branch, friendship if he's on someone else's branch, and strategic ambiguity if he picked Others.
Broadly speaking, that seems like what we should expect from Season 3. You'll still see all the LIs in story scenes, but you won't see their lewd scenes unless you're on their branch. And you probably won't see most lewd scenes for the side girls unless you picked others.
Unfortunately, writing more paragraphs isn't going to be enough; DPC prefers to show the action in lewd scenes rather than merely narrate it. That's a good thing in my book, but it does limit how much we can fool around with all the side girls. I think the total amount of lewd content will probably be about the same as we got in Episode 7 or 8 (maybe less Madame Rose if we're very lucky), but you'll need more playthroughs to see it all.
Eh, sorry, but I'd say her eyes are as bland as the rest of her.
I'm so confused! Should I be proud or sickened that I recognized her straight away?
