knot cannot serve future DS algorithms
Add this to your zone (in my case nohats.ca)
weird-ds.nohats.ca. IN DS 12345 42 42 656e636f64696e67207765697264207468696e67730a
The zone will fail to load.
This means older knot's will never be able to serve newer DS algorithms. This would slow down future deployment. I see no good reason to reject this.
