UIMENUFCN in 2014b

In the update to 2014b, the function uimenufcn was altered.

I am trying to achieve this functionality: uimenufcn(gcf,'EditCopyFigure')

According to Matlab Support (via a different answer, "NOTE: The UIMENUFCN function is not documented and we cannot provide technical details regarding UIMENUFCN.")

That's all good unless it's removed suddenly, and without warning.

What is your question? Undocumented functions are known to be not supported. If there is no documentation about them, where would you expect a warning to be published?
