Automatically set keyframe type

I've always wished that creating keyframes with the pose breakdowner would automatically set the keyframe type to breakdown so I could easily distinguish timing adjustments from key poses in the dope sheet. I'm toying with the idea of implementing this as it would be relatively straightforward (at least when auto-keyframe is active to keyframe it immediately after the breakdowner; harder if I wanted the method of posing to be "remembered" for when I keyframe it later).

I could add a configuration setting to enable or disable this behavior. Curious to know if anyone else has ever wanted this.

Going a step further (and maybe a step too far :) one could imagine logic that attempts to automatically identify moving holds, jitters and (maybe) extremes based on the shape of the curve, and automatically set the keyframe type in those cases too.

Please feel free to explore this idea with me.
