@StevenLuMT - what is the justification for removing this method? We added it as part of PIP 180. I think we should consult with @Jason918 before we do this kind of cleanup up, as this feature was only just added in November with #18265 and might not be something we should remove.

@michaeljmarshall Thank you for the reminding. It's OK to delete this. I add this method during locally updates. It's not used any more.
