Yes, hundreds of owners who fly competition aerobatics.
In competition aerobatics you are constantly and repeatedly going from
full throttle to idle. There is no in between setting.
The only time you fly at a given power setting for any length of time is
when you are flying from one contest to another.

Also maneuvers such as snap rolls produce some pretty stong forces on
the front seal and bearings when done at full power. That prop is
like a big gyroscope.

That's absolutely true, especially with metal props. Guys with metal props
have to really watch their gyros and keep a close eye on the seals.
