What i mean, every node is the same, no mongos , you just connect to one random mongod and it handles the mongos funcionality.

So if you grow, you add 1 node, not a replica-set(that could be 3 nodes if you have 3x replication)

Unfortunately, this would break compatibility with existing MongoDB applications more than we would probably be willing to do. However, there's no reason RethinkDB couldn't use Fractal Tree indexing instead of B-trees, given some engineering effort.

but rethinkdb doesn't have range-sharding (they had it but they are/did change it to random(id), also no sharding(custom_field))
