alt Hacker NewsThis domain needs some better ontology and taxonomy, there's so many overlapping and conflated terms whenever I hear about it. To name a few:
- Feature Flags used as Configs;
- Configs used as Feature Flags;
- Live Ops, Control Groups, Experiments, Analytics, and more bundled as "extras" to Feature Flags as if they were the right parent term;
I think classical systems/engineering see feature flags as boolean state in some data store, but these PaaS are pushing it as a new thing and struggling with marketing.
I wish they took the gaming companies lesson and started using the term "Live Ops"

To me there two type of feature flag. For tech and not for tech.
If you have good CI/CD practices, an ENV for the environment has what feature is simplest. No new dependencies, change code commit deploy.
Non-tech folks need something else that allows them to switch it on and then off. For a variety of reasons.
This article does exactly that, you might find it an interesting read: https://martinfowler.com/articles/feature-toggles.html
