The --config argument is pretty useful (for me) when debugging, so I
don't support its removal (at least that's what we usually mean by
deprecation, a precursor to removal).

Until someone (TM) is inspired to work through what variables to
propagate, and how to populate them (whether it suffices just to
preserve the environment, or whether values have to be synthesised), we
could certainly update the docs for --config to direct people to use
environment vars if they need propagation.
