I think that it should not be reset (not resetted lol)
I believe that the original spawn should remain the same with a few tweaks.
1. Remove all shops from the spawn area, and make the mall the main sale area. (could also put shops for basic items at SRN railway stations, just a non-connected thought)
2. Modify the farms and ensure functionality.
3. Create a "noob hall" to provide new players with a few startup items
3a. Basic Leather or Iron non-enchanted armor
3b. Basic low-level wooden or stone tools and weapons, also non-enchanted
3c. 1 choice limited to 1 stack food items such as potatoes or carrots, this would allow the player to eat, as well as plant these items and begin a farm.
To remedy the crowded historic builds issue that some people seem to have, we could create Spawn outposts labeled by year (e.g. /warp SOP2107, /warp SOP2018, etc)
This would allow the existing history to remain, as well as chronicle the new generations. Also, these locations could be placed many thousands of blocks away from the original spawn and literally open up whole new worlds! No one would lose their progress by creating a whole new world/seed but everyone would have new space, and the timeline would be accessible! This could also occur in concentric rings around the original spawn for a really cool flow. For example, SpawnOutPost2017 could be 20,000 blocks to the north. 2018 could be 20,000 blocks to the East, 2019 South, 2020 West.
