I've read more than a few horror stories involving terrible GMs who have their DMPCs mind control PCs for really creepy (usually sexual) reasons. I would assume that @overgeeked wanted to avoid something like that.This is where someone might look at your list and wonder if there's some cynicism at work. You don't want a common fantasy trope (magic that enchants or manipulates the will) used against the PCs (or specifically your PC) but are OK with using it. If I had a player coming to me with that, then I'd be wondering about their commitment to the principles of free will/control rather than fair play in a game and be tempted to take it right off the list of PC abilities as well so that it's never a question at all, for anybody.
In this particular case, though, I'd ask them to define mind control. In one game, I had an NPC monster cast enemies abound (or as I like to call it, create temporary ally) on a PC. Would this count as mind control? Does something like charm person count, which is short-term, or are we talking full-fledged domination that's off-limits, like with a vampire or 'cubus or nymph?
