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.
