For the os-refresh/collect-config I suspect the answer is NO - at least, we aren't using these any more in the 'normal' tripleo deployment for a good while now, since we switched to config download by default. We haven't even created an ussuri branch for these [3] and no one has shouted about that (or at least not loud enough I haven't heard anything).
TripleO doesn't use them, but I think Heat still does for the support of SoftwareDeployment/StructuredDeployment. I've added [Heat] to the subject tags. It is as least still documented:
which shows using the os-*-config elements from tripleo-image-elements to build an image with diskimage-builder.
