Hello, it has been a long time and no one has commented as to whether this PR has merit.
Since the time I opened, I have noticed that other classes could benefit from having a simple interface to do the formatting copying (all of these rPr kind of objects).

Should I pursue this further or should I simply have this as a patch set in my systems that I would need to apply post upgrades?
What could I do to get this kind of change to an acceptable state if you think there is benefits to my proposed changes?

Thank you for your time and effort!
