Todd Fleming: scope originated as part of sharding, which was later
It can sometimes make indexing easier. Other times it doesn’t have any
In other words, the sharding method of enabling parallelism detailed in the whitepaper is no longer applicable, and parallelism will be achieved via sidechains. This doesn't make use of scopes, as they're different chains which are identified by their own properties, so scopes are just a tool to separate your tables for your own convenience and indexing preferences on one chain.
At the moment, sidechains are not documented in the whitepaper or in any EOSIO resources besides a rather old post from Dan on IBC, so I assume the main resource for reading about them remains the original paper that introduced them.
