This worries me. Not because I think there is any chance of loosing coins but because you don't know that there is no chance of loosing coins. Spend transactions are either mined into a block or not. If they are not being mined you can just stop broadcasting that transaction and mining pools will eventually forget about it and you can send those coins with a fee. How exactly is there a risk of "loosing" coins, then?
This fork is merely 3 lines of code which turn off a single limitation which forces you to pay a fee even when it is not absolutely necessary. That is not rocket science.
You seem to have misunderstood what I wrote. I just said that there is never a risk of loosing your coins just because you didn't pay enough of a fee. You just remove the transaction using pywallet and wait for the mining pools to forget it. Then you can redo the transaction again with a fee.
