Okay.

The "path completion" analogy and the dotted configuration variable
analogy (below) don't really help me find "--no-" less weird. We're
used to "/" as a separator in paths, and "." a separator in
configuration variables, so they are easier to digest than "-" somehow
being a separator for --no-<option>.
It _might_ feel as bit less weird if it was presented as --no-<option>
or --no-{...} or --no-<...> or --no-... or something, but those seem
pretty weird too, so perhaps not. Anyhow, it's not a major issue; the
--[no-]foo idea seems pretty intuitive, but if it can't be easily
implemented, then falling back to your --no- idea makes sense.

Just wondering out loud (again): add.<var> | add.{...} | add.<...> |
add...; those aren't very attractive either, so plain "add." may
indeed be best.
