For what it's worth, Knot DNS is fixed by default. I know because the
first setting in my knot.conf file is "answer-rotation: on". :-)

NSD also has a "round-robin" setting, which is also off by default.

So other nameservers do support fixed order, but I personally don't
use it and don't mind if you remove it.
