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).

{
    nFee = 0;
    listReceived.clear();
    listSent.clear();
    
    CAmount nDebit = GetDebit(filter);
    if (nDebit > 0) 
    {
        CAmount nValueOut = tx->GetValueOut();
        nFee = nDebit - nValueOut;
    }
    
    for (unsigned int i = 0; i < tx->vout.size(); ++i)
    {
