Comment (by acat):

 Note: I missed a path (which should not affect us), so trying to get this
 followup landed too: https://phabricator.services.mozilla.com/D74626.

 The issue is that already cached entries (when `network.dns.disabled =
 false`) may result in network connection much later when
 `network.dns.disabled = true`, as they are asynchronously renewed when
 they expire. This should not affect us in the sense that if we set
 `network.dns.disabled = true` right from the beginning, the only cached
 entries would be IP literals, which never expire.
