I think that option #2 also improves write scale, though asymptotically rather than horizontally.
In option #2 one of the consistent routing choices you can make is to channel all writes to the master. Then we effectively have a write-master plus read-slaves arrangement which is a reasonable pattern for scale-out. I think Alex said it best that cache sharding is a reasonable interim strategy until such point that graph sharding stops being an impossible problem.
