The new `getrpcinfo` shows a list of the active commands and the duration each command has been running. This sounds like a good place to report a completion percentage for any command doing a blockchain rescan, to solve [this problem](https://bitcoin.stackexchange.com/q/83236/90721).
{
    std::shared_ptr<CWallet> const wallet = GetWalletForJSONRPCRequest(request);
    CWallet* const pwallet = wallet.get();
    if (!EnsureWalletIsAvailable(pwallet, request.fHelp)) {
        return NullUniValue;
    }
    if (request.fHelp || request.params.size() < 1 || request.params.size() > 2)
        throw std::runtime_error(
            RPCHelpMan{"lockunspent",
                "\nUpdates list of temporarily unspendable outputs.\n"
                "Temporarily lock (unlock=false) or unlock (unlock=true) specified transaction outputs.\n"
                "If no transaction outputs are specified when unlocking then all current locked transaction outputs are unlocked.\n"
                "A locked transaction output will not be chosen by automatic coin selection, when spending bitcoins.\n"
