Yeah, at this point we will probably need a discussion and explanation
of the protocol behavior this is adding, such as how to negotiate
different compression settings.

Unrelatedly, I suggest skipping the addition of -Z options to various
client-side tools.  This is unnecessary, since generic connection
options can already be specified via -d typically, and it creates
confusion because -Z is already used to specify output compression by
some programs.
