A reader emailed me about this question, and a few days later I ran onto this. I'd have to say that generally speaking Anglican divinity frowns upon it. Bicknell's treatment is one of the best.
That being said, I would say it's somewhere near adiaphora. Even if it has no solid root in either Scripture or Tradition, it's hard to see why it might be harmful, and a case can be made that it can certainly be beneficial to Christian devotion. Bicknell even seems to admit this.
If you want to wade through the long video to find his comments, REC Bishop Ray Sutton's thoughts are interesting.
