Microsoft deprecated the File History API

I was looking back at the File History API that I had worked with previously and noticed that the new header files are saying it's deprecated. FhCfg.h has instructions like #pragma deprecated(IFhConfigMgr) and functions in FhSvcCtl.h are have notes like:

__declspec(deprecated("FhServiceOpenPipe is deprecated and might not work on all platforms. For more info, see MSDN."))

I'm looking at header files from the SDK for Windows 10 build 17134 (version 1803), while the version from build 10240 (version 1507, the original Windows 10) does not have the notices. Weirdly, there does not seem to be any mention of this deprecation in the documentation of those functions nor anywhere on MSDN that I could find by searching.
