idk, feature flags for the entire application seem ok to me.
The issue is when we want to add feature flags for part of the users, or only on a part of the application flow. Then it will become a mess.
Where I work, those feature flags are used to deploy a feature for a single application "run time", i.e. a country, which has its own cloud and everything.
I’d agree with that. A quick skim says there’s nothing in that list I haven’t heard elsewhere. That doesn’t invalidate TFA, it is advertised as “collected bits”. But most does not appear to be original with the author.
