This will be such a nice component!

Superfluous newline here

[Squareys]

Maybe either add comments like 0 /* this object */, or an enum, such that this reads mode == Scope.ThisObject

[Squareys]

That enum can also be exported and this.scope can be typed to it (I think), such that people can easily add them at runtime and just this.object.addComponent('xr-active-switch', {scope: Scope.ThisObject, ifInXR: Action.Activate});

[Squareys]

Ah, there it may make sense to make the defaults Action.Keep, since the most sensible default is that leaving out an explicit configuration just does nothing.

[Squareys]

And maybe we call it Action.None? That's a bit clearer than Keep, also for the enum value 'none'

[DavidPeicho]

getComponents(XrActiveSwitch.TypeName) already achieves the filtering

[DavidPeicho]

Since you only use them here, no need to store on the class:

processChildren(obj: Object3D, out: Component[]) {
    // Push into `out`
}

collectComponents() {
    const components = [];
    processChildren(..., components);
    return components;
}

components is only temporary, doesn't need to live in the class
