What I value is the ability to focus on braking and line choice at low speed without worrying about a stall. Remove one job from the left hand and the rider has more capacity from corner entry to exit. A centrifugal clutch will not always engage at exactly the instant a rider wants, though. Keeping the lever is the right escape route when the pace rises.

The manual lever matters because it can fine-tune engagement timing.

You need to remember it cannot hold the bike in gear when parked.

If starts and stops are clutchless, does that make hills easier too?

Hill starts may be easier, but parking still needs a brake solution.
