To improve compatibility of this proxy with existing and future solutions, I think it would be much better to use the slot defined in EIP-1967: Standard Proxy Storage Slots. @pi0neerpat Can you explain the reasons why this was explicitly decided against? We’re trying to move said EIP to Final state and it would be good to have UUPS on board.
We really do like this model and want to provide an implementation of it in OpenZeppelin Contracts but the choice of an incompatible storage slot sticks out as a problem for us. For inclusion in OpenZeppelin it would also be necessary to move this EIP to Final.
