EAF uses debug registers which limits its usefulness and the ROP mitigations are becoming less useful because of CFG (control flow guard). Although the latter does require applications to be recompiled with the latest Visual Studio (and Opt-In to using CFG which is not enabled by default). It's not really surprising seeing Microsoft retire EMET considering you can get nearly the same kind of coverage on a vanilla Windows 10 install.
I made a rough guide as to the layout of the MitigationOptions QWORD which controls these mitigations:

There are Microsoft provided functions which can also enable these mitigations[1][2] when compiled into the code. Also lets not forget that for now EMET still works fine with Windows 10.
