I see people mentioning feature flags, is there a framework or pattern for feature flags?

Imagining python where people use argparse as a library I imagine this can be a huge list of CLI arguments, or values to be parsed from a config file, or from the environment, that have to trickle down to a lot of parts of the system full of

  if not feature_flag:
    return

I am imagining some big django app, or even something like elasticsearch which is a big java app.
