An effect is an effect, regardless of how it is achieved.
The real question is, 'Is the picture good'? If the answer is "yes" then it matters not whether it was made creatively by holding a bouquet in front of a lens or with Photoshop.
Though I like the way a knowledgeable photographer used lens optics for a creative effect, the picture is no better or worse because of it.
Interesting yes, in camera no. In FRONT of the camera yes.
I meant "in-camera" to differentiate from an image effect that was achieved after the image was recorded, i.e. using a brush/filter with photo-editing software. "In-camera", at least to me, means "at the time the image is taken", even if it involves something external, such as jiggling the camera, etc.
