You know, if we're gonna do that, "Honeypot" and "Honeynet" have to go. They actually still mean things in parts of the English-speaking world that are seriously racist.

Hey, if the author dislikes "master/slave" in computing, maybe s/he can get us all to use "manager/employee". Functionally, there is very like literally when things go as planned. Oh wait, nevermind, we dislike word-mincing.

Words change. Perhaps we'd prefer "Roman"/"Slav" dynamic? Oh wait, the Romans took so many Slavs as slaves that their word for "people" became the Roman word for "slave".

"Foundational" / "Associate" could work well. Like the way "associate" in a law firm used to mean something. Now even the bagger on their first day at the grocery store has "associate" on their tag.

I dont care. Just make sure it communicates heirarchical data as is necessary to discern such in practicality.
