Hey @albist, thanks for your support!
In case you missed it, the association published a forum post detailing a Standardized method for distributing incentives on Morpho Blue markets that will be used on the wstETH markets. It should answer your questions about incentives.
Regarding market creators, Block Analytica is creating the WETH(wstETH) market and Steakhouse is creating the USDC(wstETH) market. Note that market creation is permissionless, so anyone can create a market. Vault managers then decide which markets to list in their MetaMorpho vaults.
