I feel like this is a solvable problem: 1) make feature flags be configured to have an expiration date. If over the expiration date, auto-generate a task to clean up your FF 2) If you want to be extra fancy, set up a codemod to automatically clean up the FF once it's expired

I don't see the problem with developers using flags for configuration as a stopgap until there's a better solution available.
