Point is, if someone is using double reins, then the curb rein should be pretty much loose unless in action, which would only be when necessary. So therefore, the only time this bit could be particularly severe is if someone is over zealous with their hands, or reliant on their hands for balance.
If someone is using roundings, then essentially the curb action is hindered and less effective anyway, so 'safer' for less considerate or experienced riders.
Personally I have only ever used straight bar pelhams as I find the nutcracker action of jointed a bit too harsh coupled with the curb (I always used double reins unless jumping) and poll pressure.
I think spilt riens are better than roundings , can you still get them I have not seen any that I can think of for years.
