Why is ObiRopeCursor handling input?

[the80srobot]

I'm using the new input system in Unity, which means I tend to discover random places where asset store packages try to use the old Input.GetKey API, because it now throws exceptions.

One place that I was surprised to find Input code in was the ObiRopeCursor - it's not placed in a Samples directory, so it looks like a reusable class, but it specifically listens for the Q and E keys to control its length. Is this a mistake, or intended?

Thanks.
