I’m curious if certain QOL updates might come into the game? nothing crazy but just like quest journal showing you where in the questline you are? Maybe also having skill menu’s when you click on the skills? Just basic things that objectively improve the game.
Probably not. This is a preservation server
Skill guides and quest journals were added to RS2 a few months after the version that Lost City is based on. For example: Update:Quest Journals and Chompy Hats - OSRS Wiki
So we’ll get these relatively soon in the grand scheme of things. But we’ll only get the QoL that was added to the original game, in same order it was originally added.
oh, so you mean there will be updates over time? to which date are they planning to update to?
Honestly i wasn’t even sure we’d get the basic quest jorunals even . 
See here for the answer: Beta Launch: What's next? | 2004Scape
- Are you going to work on future 2004 updates, maybe even 2005+?
Exactly the goal. This is a progression server powered by an effort to openly preserve the game. When we cross a milestone to another year, the previous year will be copied and run as a fork while the main server continues on. If you want to stay in a previous year, you can. You do not have to restart from scratch to play in a future year.
So we will get updates - and skill/quest guides come relatively soon. Quest journals were added in July 2004: Update:Quest Journals and Chompy Hats - OSRS Wiki and skill guides in September 2004: Update:Skills, Duels and the Kalphite - OSRS Wiki
