I second turning it off.
Further, IMO the header should be renamend to something like X-Debuginfo: .......
IIRC "Warning" has often confused beginners (me too).
"Warning" is an already standarized header in RFC 3261. Does the added debugging information conform to the grammar of the Warning header? Examples:
Warning: 307 isi.edu "Session parameter 'foo' not understood" Warning: 301 isi.edu "Incompatible network address type 'E.164'"
