Control-M Integration - EM API deprecated

When contacting BMC Support regarding xMatters case 170382, the following statement was made by Cody Belcher, BMC Customer Support:

"Also, I wanted to make sure you are aware that EM API, the component used for this integration, is deprecated and will be removed in a future version of Control-M. Due to this, you should work to migrate toward using Control-M Automation API as a replace for EM API."

This is the first we heard about this. I am told by xMatters support that "it would need the consulting team to make updates".  Is someone already working on this replacement?
