I worked for redhat in a past life and I recall having to do this for documentation back in 2003-2004 to comply with a California law[0] regarding vendors to the government.

It's been a long time but I'm pretty sure I remember changing "master/slave" to "primary/secondary" in a bunch of bind docs.

I feel as though primary/secondary doesn't define the relationship properly.

I, for one, think this is all getting ridiculous now.

The chosen terms don't define the relationship. The documentation defines the terms in the given context, including their relationship.
