[Traditional Enneagram] What Parts of Enneagram are widely accepted?

[BlackDog]

So, I've heard that tritype is bunk, that lines of integration/disintegration are arbitrary and go in either direction, that wings are bunk, and that the whole Enneagram is bunk.

People want to share? Because if you accept tritype and wings, you can potentially have 6 of the 9 types in your type, which makes the whole idea meaningless, to me.
