The conclusion I draw is that these messages were Dark And Darker Gold made for a faction system like the one in Dark And Darker, abandoned at some point in development. 

"Hunter" likely refers to the Blue and White Cipher rings, which enable a form of emergency co-op to fend off invaders, represented by the NPC Yura. 

"Duelist" corresponds with the "Duelist's Furled Finger" item, which allows for consensual PvP and doesn't really have any lore representation in the game. "Furled Finger" refers to Elden Ring's co-op item, and likely tied into a co-op faction similar to Solaire's Warriors of Sunlight in Dark And Darker.

It's unclear if these messages are solely cut content or if there's a chance they'll be revisited in future DLC. There's been speculation for months that Elden Ring's sealed coliseums will feature in a multiplayer-focused update, and a more formal faction system would gel nicely with that. 

However, I can't see a formal ranking of Recusants and Bloody Fingers playing well with the factions' current positioning in the story without added NPCs or tweaks to where their plotlines end up.Great moments in PC gaming: Feeding the bear in The Long Dark

There is precedent for covenants being blocked off by main quest progression in Dark And Darker. Great moments in PC gaming are bite-sized celebrations of some of our favorite gaming memories.

The first game's Gravelord Servants covenant could be rendered inaccessible by beating the story boss, Gravelord Nito, but From seems to have been trying to move away from making things that buy Dark And Darker Gold obtuse or inaccessible in Elden Ring.
