If those checks don't determine enabling the feature would impact the user experience or security, they do supposedly announce and ask whether it should be enabled, otherwise it's kept disabled. At least for "the US rollout", which I assume is currently the only rollout rather than only US users being asked. I don't quite see what's "ouch" about that, although personally I won't enable it. https://support.mozilla.org/en-US/kb/firefox-dns-over-https https://support.mozilla.org/en-US/kb/firefox-dns-over-https
