My bad, I did not realize you were refering to left-hand-only signaling.

I gave up on that a while ago. I decided it is much better to use a signal more people are going to understand (pointing with the arm on the side I am turning to).

What made me come to this conclusion was when (despite knowing what the "by the book" signals are and even occasionally using them myself) I was driving behind a guy on a bike and thought he was waving to someone rather than giving a right-turn signal. If I am slow to get it in a real world situation, I'm pretty pretty sure 95% of the drivers out there are even slower (if they get it at all).

But either way, if I ever do need to stop quick, I am going to have my hand back on the bars before I start braking hard.

And honestly, I don't think it really matters THAT much which brake you squeeze too hard with only one hand on the bars. If, in a panic situation you are hitting the back brake hard enough to lock it up (which is where the "margin of error" comes from) you are probably going to lose control anyway.

So while I agree that the rear brake in general is more forgiving and has a greater margin for error, I don't think it matters a whole lot one-handed. If you don't have the immediate, natural reaction to have your hand back in the bar before a hard braking, I think you may be in trouble.

My original point was that having a bike with a setup reversed from the norm where you live is far more likely to get you in an accident than the hair-splitting differences we are talking about here.

The silly thing here is that we are both arguing for left-front. You becuase of signalling, me because it is the norm in the US.
