There are some "Gray" areas where it could be beneficial... as in when a new engine is installed. But, it would be too easy to use it for dishonest reasons.
Now... if the boat was never registerd, and/or sold... then it would be a moot point. The total time, and owner would be empty or zero.
As far as the VIN (HIN) that doesn't change since it was a number assigned when it was manufactured.
When you buy a new, unused MPEM from BRP... that is all blank, and can only be set once. That also includes the DESS system. If you never set it... it will start with any lanyard. BUT... once programmed... it can't be turned off again.
