My understanding was that "rolling" was sort of a break-in process and a similar effect would eventually be had after enough hits. Does "rolling" impair the metal structure such that it is more apt to break apart?
As for shaving, once the problem is big enough I suspect someone will figure out how to make the cap tamper proof as part of the certification (of course someone will come along and figure out how to tamper without getting caught).
You are correct in what you are saying in regards to the rolling process BUT, it stretches the molecules that the bat is made up of. So even though it is 'breaking in" the bat, because it stretches the molecules it causes the exit velocity to jump. No matter what you did naturally you could not get a bat to behave as a rolled bat if broke in naturally.
