I kind of think analog input for gaming wouldn't work that well on a keyboard. The keys would need to have a good amount of resistance without tactile feedback to make them work well as something like a gas pedal or steering wheel, but doing that would likely make them feel very mushy for actually typing on. Most likely, these are instead designed to be better for typing, and not so good for precise analog input in games. And while they might work for that, it seems like analog keyboard keys wouldn't be as good of an input method for something like a racing game as a gamepad or steering wheel would be.
You may well be quite right that other peripherals are better for certain types of input. But not everyone will want to (or be able to) buy those things. Keyboards like this give you analog input with no other gear. It's just right there under your fingertips.
Also, let me address your other note, because I think there's a lot of misunderstanding on the feel of the keys. The switches themselves feel exactly the same as any mechanical switch. Note, for example, that the Aimpad R5 just uses Cherry MX Red switches. Therefore, there's no mush or anything.

The magic is in the sensing method. Both Wooting and Aimpad use optical sensors to detect the depth of the switch stem and translate that to analog input.
And you can just toggle off the analog sensing when you don't want it, and it will feel and perform exactly like any other mechanical switch.
You do make a good point, though, about the degree of force. If the switch is too light, you may feel like you don't have as much control as you'd like. But make them require too much force, and they're crap for typing. For that reason, MX Blacks (and their ilk) might be an ideal compromise--60cN instead of Red's 45cN, but still linear. (You're right about that too--analog switches need to be linear, or else what's the point...)
I've actually thought that Topre switches would be ideal, because they have that deep 5mm travel...
