Dunning-Kruger effect seems like a weird accusation to throw here. The whole basis of it is "a false sense of superiority", but the author is clearly willing to engage on this issue.

I think a better way of terming this would be that you have concern the the author might not have enough domain expertise, which is very different than being incompetent.

This gives me pause that Maud isn't right for a production system at this time, but is that so surprising for a 0.11 library?
