With sufficient deference given to the more capable, I don’t see a problem with a lower average.
Maybe you’re worried about the phenomenon of 9s receiving numerically many upvotes from easily-impressed 8s, with 10s’ contributions not being understood as widely. I don’t think this is too much of a concern if people who have the best ideas and judgments improve their teaching.

Except that you need to be careful that that lower average doesn’t result in goal dilution.
