Edit: you said brakeless though, I wouldn't ride brakeless and I'm not advocating it, I'm just making the point that there is no evidence. You're asking me to make a judgement and I think I know the answer, but I have no proof.
Get your own evidence. Do a series of brake tests (down hill, emergency stop, slowing for car/corner etc,.) with your current setup and then remove the front brake and do them again.
If you cannot stop as quickly and effectively without the front brake then you have your evidence. Whether any increased stopping distance would cause you to actually have an accident is irrelevant, but the potential for accident would be higher, therefore it is more dangerous.
