I was thinking mainly for when the version is upgraded, as it was in this case. Not sure if it was me (since I didn't backup), or if it was by design, but my hotkeys didn't automatically come over to 3.0 from 2.6.b5. I know I got most back from it, and I know I can get to 2.0 to get the rest back, but, it's more of an ease of transfer mode of thought on my end.
