See my edited response. The access will likely be handed over. Again, the community will need to determine those decisions if and when they wish to take ownership.
indeed this kind of thing should not be done lightly. handing over a wallet only means that more people have access to the private keys that control it and so more potential for bad actors to steal the funds.
ultimately the best thing to do would be to hard-fork and move the funds over to a multisig wallet controlled by 3+ (ideally more than 5) people where it takes a clear majority to actually confirm withdrawals.
