No.
For me the new mode approach is OK.

Thats what I did in the first place.
However, I found some potential problems with existing code:
For example, a call to setCenter defines the mode to USER_DEFINED_CENTER
So a User doing the below code would get unexpected results.
And removing the mode switch in setCenter would probably break existing
code.
PagedLOD plod = new PagedLOD
plod->setCenterMode(UNION_OF_BOUNDING_SPHERE_AND_USER_DEFINED)
plod->setCenter(my_center) <= implicitely sets the mode to
USER_DEFINED_CENTER
The setCenter method could easily be adapted to not change the mode if
it's already UNION_OF_BOUNDING_SPHERE_AND_USER_DEFINED.
There is also a risks of unwanted results in existing code that call
node.getCenterMode()
The serializers are the only common place that I'd expect code to be
calling getCenterMode(), I wouldn't expect most users to be effected. Do
you use getCenterMode() in your own code?
