Idiots running Knots with the defaults can't even build a full block. I happen to like knots because it gives me the control to run an opinionated node, but if you just run it with the defaults then you're just running the opinion of the knots devs instead of the opinion of the Core devs. What's the point in that? And who wants to mine an empty block? The default settings are too restrictive and discard a lot of legitimate financial transactions.
