@aeonofdiscord Any user-editable fields displayed consistently to an audience eventually becomes at least somewhat Content, at least sometimes.
(e.g. https://nox.im/posts/2021/0724/hosting-tor-hidden-services-with-vanity-onion-addresses/ )
But making it clear it's specifically NOT the Primary Content -- making a specific separation -- allows it to also NOT be content, if the author doesn't want it.
That's important, to give them that choice.
