I've been talking about this with other players that I know and giving it a fair bit of thought myself, but what kinds of quest updates do people want to see?
Personally, with the supposed timeline for Tarkov being Factory expansion (new scav boss), followed by Lighthouse (entirely new map), and then Streets, I'd really like to see more quests added that give me a reason to go to them. The Kappa questline is already good enough at this point in the game's state, but I'd love to see questlines similar to the Sanitar line. Peacekeeper is trying to locate xyz for xyz reason and is enlisting Skier and Prapor to have you look around Reserve. Mechanic and Jeager are working together after hearing about the new Factory scav boss and want you to put an end to him. Therapist hears about a well-stocked pharmacy near the coastline and sends you to a lighthouse nearby to gather resources.
I think that the lifetime of wipes would dramatically increase if there were fleshed-out questlines that point PMC's in the direction of other maps than the standard Customs, Shoreline, Interchange, and Woods. The other maps have a few quests associated with them, but nothing substantial IMO.
