At my work, I have a somewhat clever (or idiotic) technical solution to the problems of feature flags: they are actually implemented as feature modules that monkey-patch the base application in runtime.
There are a few benefits: removing features is dead simple, just delete the whole feature module, and there's no conditional branching in the base application.
There are some drawbacks too: the base application must have entry points for the feature modules to overwrite. Usually the default values are no-op or some default behavior. Features also must implement setup and teardown, which can take longer to write than a conditional.
