Adding a Haptic Metronome to the Watch

There is some Apple sample code for a metronome:

...which could be adapted.

Forum user @rnodern asked a more advanced version of your question:

..but they haven't answered with any progress, so I don't know how serious they are.

As I said on that thread, I guess it is technically possible, but I wonder if it will work in practice?
I thought Apple Watch haptics might help with navigation on the motorbike, but in practice I rarely notice the buzzes.
So I wonder if it will be noticeable enough to follow, while playing an instrument (or in a band).
