Wrap deformer need to improve in algorithm to get better smooth result and not clunky result.
here example :


one of the dev in naughty dog show their Green wrap deformer :


you can see the part at 00:57

with green wrap deformer we can put any object on curve surface without distortion.
----
here the problem :
wrap + shrink wrap on curve shape


when I put it on curve shape as you can see it all get distortion with bad smooth result.

here half sphere with bend only see how smooth but with wrap deform on half sphere and bend it give me bad result... so wrap deformer need more improvement.
a topic in polycount show blender give better result :

What important we need to place objects on curve surface without distortion the object.
