I think you missed the point that Marco was trying to make. When you are talking about a high proportion of filler text, it frequently is an example of steganography, something that has been discussed quite frequently in the context of the VMS.
Whether you came to the idea independently or not, it's still a good idea to use (and acknolwedge) the terminology that others are using (and which are part of the cryptanalysis lexicon) for these forms of codes. And also to acknowledge that the diplomatic ciphers (as collected by Tranchedino) do not include large amounts of filler text (are not in any way steganographic).
