Yes and if you have them in the wrong order in the tree, or a little setting (like an object reference) wrong on one of them it doesn't work right and it's really hard to find out why. Also what each one is actually for. The names are far from clear to me.
It's documented but I don't find it very clear. In the end I've started using the Oculus toolkit rather than the openxr one as it was the only one I managed to make work. Some things are implemented weirdly though. Like the fade to black when teleporting, it just draws a black rectangle in front of your face but that doesn't work if you're not looking straight ahead because you can look past the edges of the rectangle. So then I have to go and fix that.
I understand everything needs to be flexible, in an engine you can't make assumptions otherwise you can't do things that deviate from the norm. But this seems to be overly complicated to me.
