I believe similar wording exists in almost every flight manual.
Exceedence of Vmo to ensure the overspeed warning is properly active is a routine production flight test activity on many types, too.

Any Part 25 aircraft with a Vmo "cut back" below 8000ft/10000ft almost certainly has a similar design constraint. There's nothing else in the design requirements which would drive an abrupt...
