Does the single channel ABS on the base variant compromise safety?

On the base variant of the Royal Enfield Classic 350 S Redditch Edition single channel ABS is offered, while dual channel ABS is available on higher trims. That has caused a debate among riders over the safety implications of opting for the base model. However, they say that single channel ABS, which works only on the front wheel, is sufficient for most of riding conditions and keeps the cost down. However, some argue it is not necessary, and use of dual channel ABS (that operates on both tyres) is vital for the maximum safety, particularly in the emergency braking situation or on slippery roads. Many potential buyers are conflicted between cost savings and possibly extra safety features. Is the single channel ABS really enough, or should safety conscious riders always go for dual channel?
