Here's a video for it likely ship building. Notice the strap on the tension side of the bend.

Yes, the strap is applied before the bend to limit stretching of the convex surface of the piece.
Raising a splinter is likely the sole concern of the shipwights.
With a bow limb, a strap applied (prebending, and in the location Dave shows above) will compress the limb's back, maybe unduly if it is expected to serve as the tension side of the limb.
Experimentation might be neccesary with similar methods to bring a bamboo working limb into the best balance of tension or compression qualities for becoming a game changer.
As bamboo excels in tension already, My guess is that whatever works best for the belly side of the limb will be where you find a game changer.
