As an outspoken Radical Centrist, I agree mainstream Centrism is no where close to Radical Centrism. It's moderates on the Left who get flagged as "Centrists". Radical Centrism is kind of nihilistically scientific, so it's only conservative in the sense that order restricts non-pragmatic ideas that are advocated. What works, even after compromising some consensus, may not favor equality. That said, there is no religious or traditionalism to it unless you technically want to include scientism as an alt-theocratic belief.
That said, exploring new ideas and being open minded of new solutions is inherently in line with liberalism, if not a flavor of progressivism. You have to be willing to change your opinions after acquiring new evidence, while at the same time acknowledging multiple philosophical differences on their own merit.
I personally like the concept of a technocracy because it goes side-by-side with Radical Centrism. It's extremely difficult to gauge the preferences of a Radical Centrist as they are hidden by their prioritization of getting realistic results.
