If you think about it, you'll see that the liability issues involved make it unattractive, given what you
can charge someone for the service. There is some possibility of damaging the frame, them most likely
instance being that you can pop loose the seatstay bridge if it is at all insecure in brazing.
I have not experienced personally any limitations with regard to whether 5mm or 10 mm is an outside limit.
I know that people on the forums here (other than me) who are hot to ride these frames with brifters
and 10 speed rear clusters spread them to 130 and 136 on a pretty regular basis without incident.
But there does exist an element of risk in any frame cold bending procedure, so consider yourself warned.
