The attached v3 does it this way.

Yes, there are a few but not too many.  Whenever the protocol is refererred to
and not the concept of an encrypted connection, just the applicable term is
used.

The attached v3 wraps SSL/TLS in a single acronym block, which for sure is more
pleasing to the eye when working with the docs, but I still have no idea which
version technically is the most correct.

It doesn't, I'm just not convinced that the acronyms page is consulted all too
frequently anymore to provide much value.  I might be totally wrong though.
Either way, thats (potentially) for a separate discussion.
