Depends on your definition of absurd. I think using BD50's for anything is absurd.
But I am an optical media fan, so I re-encoded the video down to 21GiB, and put it on a BD25. The source was so beautiful it even looks good after a re-encode.
EDIT: My opposition to BD50's is entirely because I'm a cheap bastard, not because I don't see the value in high bitrate video.
