Hi Loganaden,
If compression is dropped at the TLS layer, you can still do it at the layer above it.Indeed. And, it's probably a better idea to do it in the layer above.
Then how will the news server know that the client is compressing data after the use of STARTTLS where a security layer without compression has been negotiated? It cannot guess it; and it won't try all uncompression methods to see which one has been used.
Unless you are speaking of an update of the NNTP protocol to add a new compression capability (for instance with the use of a new COMPRESS command with possible arguments), that could be used by clients? Well, it will require some work to specify it. Not to speak of its implementation afterwards.
I bet other protocols would also need similar new specifications to explain how compression can be enabled.
