Group1 and group2 wikis are back on wmf.7 again (follow T293950 for details), so automatic topic subscriptions shouldn’t even exist in production (except for group0 wikis, i.e. mediawiki.org, test.wikipedia.org, test.wikidata.org, office.wikimedia.org and closed wikis). Next week is Thanksgiving, so it may happen that this change doesn’t hit production until early December.

I think we can safely assume Automatic Topic Subscriptions have been deployed as expected: people need to manually enable the feature within Special:Preferences.

I say the above given how, in the week since Automatic Topic Subscriptions first became available, ~89% of all topic subscriptions were initiated manually:
