I think the warning is dumb, and that the suggested documentation change
is insufficient. If we're going to clarify things, then we need to have
a full-on several-page doc showing several examples of different sync
rep configurations and explaining their tradeoffs (including the
different sync modes and per-transaction sync). Anything short of that
is just going to muddy the waters further.
Mind you, someone needs to take a machete to the HA section of the docs
anyway.
