We're replacing them with a more sophisticated mechanism that does
not require recompiling the front-end, and allows gradually
enabling features for specific groups of users.
Note that this does enable the hitherto gated feature
`generateCustomAliasSubdomain` (a popover when clicking your
subdomain explaining how to create a custom mask). Additionally, it
makes the interview recruitment banner gated by the new-style
feature flags, which doesn't have a flag for that feature yet. That
means it will in effect be disabled for now.
We didn't have a new data review and only added new events that
fall into the same category of data as data we were already
collecting (Category 2, "interaction data"), but it's both good
hygiene to attempt to keep this up-to-date, as well as possibly
interesting to people; hence the update.
