I started back around A6 and I played most versions since then. I may have skipped an Alpha or 2 over the years as 7d2d wasn't the only game I played. I joined the team I think In A18/A19.
I do have fond memories of certain systems like weapon parts as it gave me something to work towards apart from just exploring. The hub city at 0,0 was a fun end game goal to work towards as it had the best loot and the most zombies.
People seem to forget how broken the hub city used to be. You could easily run through it in circle maxing out the zombie spawns and eventually having no zombies to contend with while looting.
Personally, I wasn't a huge fan of LBD. It was a very repetitive system that incentivized a ton of grinding. I get it might be more immersive for some, but there is a reason LBD systems were most prominent in MMO games where they want you grinding for months paying a subscription fee.
I actually enjoy the current perk system more as it respects your play time enabling you greater freedom to level of your character where you want.
Personally, I think a hybrid LBD + perk leveling system could exist and would love to see us try one in our next game. After all, 7D2D has been going for 10+ years and many fans just want us to finish the game already instead of another major system overhaul.
Edit: Regarding POIs, I feel they are the best they have ever been in 2.0 (biased opinion I know....

)
Before the quest era, POI exploration was mostly a monotone experience and were not performant. You could easily hit the max entity count by waking up too many zombies.
I do wish we can increase the zombies counts one day but that will require some major tech. enhancements probably.
I do acknowledge some of our quest POIs are too linear. However, that gets better every update as our team gets more tools and improves in designing POIs.
We are also aware of the imbalance of questable POIs to free form explorable POIs (remnants). We have a goal to continue creating more non questables to balance the world out more.
Who knows...some of those remnants could have bandits roaming around them in the future...
