This change has no functionality impact. I agree to make this change in MdePkg library for the module development support in EFI1.10/UEFI2.7/PI1.7.
With this change, you also need to remove gEfiEventExitBootServicesGuid or gEfiEventVirtualAddressChangeGuid from module INF file if they are not used any more.
Thanks
Liming

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2446
There are many firmwares in the wild not supporting CreateEventEx, including devices less than 5 years old.
