It's an artifact of political debate done within the bubble of people who read too much theory or engage in discussions only with other political people. People who do politics and organizing in the real world are not so concerned about all these ideological nuances or asserting the value of one model over another.
If you don't have the power to change things, all these abstracts models are useless and uninteresting. Discussing how to build power in the real world is a much better way to spend your political energy.
