Having a system chain competing with Polkadot's customers (Moonbeam, Astar, Hydration, etc.) is a bad idea, in my opinion. It's just a workaround for the severe issues Polkadot has, such as poor UX. These issues have contributed to the mediocre success of DeFi-related parachains.

However, for the first time ever, I agree with Giotto. If we have a smart contract system chain, it should carry the name Polkadot, e.g., "Polkadot Smart Contract Chain" or something similar, not Plaza. The Polkadot brand should be immediately recognizable, and its success should be immediately attributed to DOT.

I agree that to improve the Polkadot brand, and knowing that Plaza is a great tool, it would be a great idea to use Polkadot as the name.
