"""Setup surfaces ask only for what a platform can't start without.

The knobs in SETUP_HIDDEN_ENV_SUFFIXES are self-configuring (/sethome) or
already correct by default, so they don't belong on a setup form. They must
still be reachable everywhere else — this is a presentation change, not a
feature removal.
