Sharding is something that is going to be need to looked at sooner or later, so It may as well get worked on now.
It is also good for contingency (27th May 2024 incident).
Shards will need to share the json and dotenv stuff, this can either be done by comparing the json data between all the files and updating all other shards as needed, or by using a centralised server (but then sharding is pointless because that's a choke point)
