Cosmos as a scaling solution, how does it help Ethereum comparing with Plasma/Casper?

Cosmos is set to launch its mainnet over the next quarter, the cross-chain platform is building an Ethereum POS zone where transactions/ddapp can be ported to the zone and easily scale upto 100x. Why there isn't much talk about Cosmos as a scaling solution for Ethereum?
