The varia suit issue didn't bother me either. It could be that Adam rightly judged that regenerating health paired with particularly ineffective enemies in that lava zone equaled there was very little threat there to face until the point at which he did authorize the varia suit's use. Or at least the writers made that correct judgment. That bit in the lava zone before she gets the varia suit was so easy to cruise through that the fact that Adam withheld the suit function from her didn't even occur to me as kind of a dick move until I saw all the blubbering about it online.
But there's absolutely no reason for Samus not to use the Varia function, or for Adam to withold it. Holding back on weapons? Sure. Holding back on a suit air-con? Not so much.
Thing is, it would be so easy to justify the sequence. Off the top of my head, either:
1) Have Samus's suit be damaged in a cutscene at the start of the section, temporarily disrupting the function. Have her push on regardless, and the function kick in at the same point it does in-game.
2) Have some kind of device or creature disrupt the function before Samus destroys it. In the case of the former, we already know that MB is working against the Federation, so it could foreshadow this.
The Varia function to me is like Samus's freakout with Ridley. Both could have worked, but both are botched.
