Thanks for this feedback. Timing of migration is certainly something we value community feedback on because it is also a strategic preference by the community. As for the assets missing - we will follow up with more detailed analysis on user positions and their asset composition.
In general, a migration from V2 to V3 decreases risk broadly in the Aave ecosystem because V3 has more risk controls (supply cap, borrow cap, etc.). In addition, V3 has more granular Guardian controls, so in times of extreme unforeseen events, action can possibly be taken faster and more granularly on V3 to protect user funds.
These are great questions. It is important for the community to align on what the intended use case for eMode is - it may not be worth the trade-off strategically. If we operate under the assumption that the community still wants stablecoin e-Mode, we recommend a shorter list of assets.
We look forward to hearing more thoughts from the community and collaborating with contributors including @ChaosLabs @Llamaxyz @MarcZeller (ACI).
