> Sure, and we should also not allow our tech debt to accumulate and we should follow every single best-practice religiously. Unfortunately, this never happens in any corporate environment. Even in great teams, tech debt often gets de-prioritized in the face of new requests. Newcomers to the team or those on their way out, aren’t always disciplined enough to clean up their flags after a successful rollout. And sometimes, these tasks simply slip through the cracks and get forgotten.

Yeah, you can make the same argument about any practice. If the team doesn't care, you cannot fix anything by doing or not doing any practice. A good team can suffer from a bad practice, but no practice can overcome a bad team.

Clean up your feature flags and definitely don't use a framework for it unless you are doing continuous A/B testing.
