@bgdlabs, thanks for this necessary clarification.
Adding additional eth correlated assets (e.g. cbETH, rETH) into the wstETH/ETH emode category will require further analysis and, most likely, updating the current configuration.
Chaos Labs recommends listing rETH and cbETH without emode at launch, and deciding on the emode listing at a later stage after further analysis and updated parameters are presented to the community.
