If it does not allow you to send without fee, probably very high risk of losing the coins exists.
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?
Ask the core Bitcoin developers. The code which asks you for a fee in that case has not been changed in my fork.
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.
