I work with data a lot, and my main issue with hedonic adjustment is that anytime I've ever made any such adjustment to "improve" a metric that wasn't purely mechanical (like a moving average or a ratio to another number), it's just one step away from making the number say anything I want it to.
The entire concept of "fixing" a metric relies on an inhuman level of self-truthfulness to not just lead you down the path of hearing only what you want to hear.
The point of metrics is that they should slap you in the face with objective reality, and improvement is just too subjective a concept.
