I honestly think if people did that, females and other minorities would complain that they're being represented as one dimensional characters for simple games as a token, and not being allowed in the major games.
Futhermore, I don't think there usually is any level of consideration because without those other female and minority opinions, nobody will speak up about it. In the design meeting I've witness, the lead will usually say, "Okay, so, John (or whatever the character's prototype name is) will be doing X Y Z)." There's no discussion over it, it just happens. The concept artist will then make the concept art based on what they're told, because they want to get paid. In a smaller game, your major focus in gameplay. You need something short and snappy. Protagonists don't get major treatments because they don't figure much into the overall experience.
EDIT: I've done in a lot of my designs with half females and half males as protagonists. For me it's not about loveulisation, but meaning. A lot of my games are based on personal experience, so if it's a male it's probably based on me, if it's a female it's probably based on a female, with their input on how they like the character to be portrayed. Not everybody is like this, however, and not everybody has the friends or experience to go off this.
