Absolutely yes. We are not talking about going back to the old insecure system. We are talking about discussing and testing a new system which serves the same purpose as the old but without it's flaws. If it turns out that another flaw shows up then it will NOT be implemented until it is deemed secure - else it will be discarded.

Securing the blockchain through research was something that made Gridcoin unique. Pure PoS was an emergency measure to address the security flaw exploited at the millionth block. It is imperative that ways are discussed and explored to return our blockchain to its unique form.
