They differ in kind from the rest of the battery: they record what OTHER
devices broadcast about themselves - hostnames, models, printer names -
so which of them run is a choice per run rather than a default to
inherit. Chips beside the mode, shown only for long runs, where a passive
listener means anything.
A listener that was switched off emits a SKIPPED test with its reason
rather than vanishing. Same argument as run.mode: a document where
local.ssdp_inventory is simply missing cannot tell a reader whether
nothing announced itself or nobody was listening, and those are opposite
conclusions about a network.
NetBIOS is the one that defaults off - at app tier it can only report
unsupported, and an on-by-default listener guaranteed to fail teaches
people to ignore the status column.
