I didn't know what it was called, but I've experienced mild Dutch Roll enough on flights, usually on the approach or landing, that I didn't realize that it was all that rare or dangerous. I had come to think of it as a normal result of wind shear.
I imagine it's a matter of degree, and I wish there was some mention of the magnitude of the Dutch Roll in this case vs what is considered normal or acceptable.
(Edited to qualify my experience as "mild".)
