This is absolutely correct, this is in the operating instructions ("if the engine reach the 3000 rpm, if the plane landed, the engine have to replace, and inspected for damage").

For example, if the Merlin XII can survive the 3600 rpm longer than 20 seconds (or the 3600+ any seconds) in dive, then it should be fixed (of course, the various throttle/boost may reduce these limits).
I'll evaluate this in due course. At present still evaluating issues brought forward in this forum that the Spitfire, in order of urgent importance:

1) is too stable
1) is too easy to bring sights to bear on target
1) won't enter into a vicious accelerated stall & spin and destroy aircraft
1) rolls too quickly in a dive above 400 mph IAS
1) shows no sign of deceleration with open canopy
1) employs "sonar" when canopy is open
1) neg g cutout does not occur quickly enough with the latest beta
1) quick engagement of elevator control at speed will not over stress and destroy aircraft
1) wings absorb far too much cannon shell punishment
1) IIa is 60 mph too fast ....oops, not any more!
1) flying a Spitfire forces one to use bad tactics and no TS teamwork
1) lands and takes off far too easily
1) prolonged inverted flying doesn't cause oil sump to run instantly dry and destroy aircraft
1) engine cutout doesn't cause CSP to go fine pitch, over rev engine, and destroy aircraft

So much to do, so little time!
