[Standards] XEP-0138 vs. TLS compression

I strongly disagree. I think that sends a confusing message to developers.

Perhaps, we should remove all the compression algorithm references XEP-138
and have it only specify the core approach. Then create new XEPs for
specific implementations: ZLIB, LZW, EXI, etc.... That is analogous to how
the IETF does it - look at how they handled RTP and the different packet

Or, we make XEP-138 obsolete and create a new one that adds EXI. IETF also
does this approach.

But having a separate XEP for just EXI for stream compression would I think
be sending a confusing message to developers.
