I think so long you have output monitoring on the actual signal then having the high power to get a transmission out despite a fault is a good thing, they are supposed to be emergency capable systems.
Not a issue for a small time ham but if someone is using it in some kind of capacity in a remote location, perhaps with snow, intense climate, etc. These possibilities will always be somewhat at odds with a neat bureaucratic solution.
I read that story before, that there was a ham club with bad heliax soaked with water that was using excessive power levels to transmit very modest signals because of losses. It sounded foolish (more like they did not do maintenance tests) but if this happened during some record snow storm or something, it could be useful. It's one of those things like when you get on the highway if the situation arises you might need to step on it for a little bit of time to avoid an accident, or say passing a semi truck, unblocking a emergency vehical that needs to respond on a narrow road, etc.. the excess speed that is not normally used has its justifiable uses.
