Let me preface my note with an "ugh!"
No, there has been no deprecation, this is an example of a bug that I'm
extremely thankful was caught.
For the record, the EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL_GUID in the spec is
correct, and remains active and used.
There was a copy-paste bug in the EFI_HII_IMAGE_DECODER_PROTOCOL_GUID that
despite the layers of checks and double-checks had somehow gotten past us all
in the development of the spec.
Let's just say that the EFI_HII_IMAGE_DECODER_PROTOCOL_GUID will be fixed
(changed) and the change reflected in a UEFI spec errata. I don't yet have a
date for when that errata will come out, but I'll push for sooner vs later.
Thanks,
Mike Rothman

Subject: [edk2] EFI PCI Root Bridge I/O and HII Image Decoder Protocol GUIDs
Dear community members,
I have just been searching MdePkg for a GUID unknown to me and - to my surprise
- I found the same GUID twice in the code base:
EFI_HII_IMAGE_DECODER_PROTOCOL_GUID and EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL_GUID.
As former was added only recently, I went to check the UEFI 2.6 specification
and discovered that even there the GUIDs match.
Now, please excuse my ignorance, but was the PCI Root Bridge I/O Protocol
deprecated and the Image Decoder was assigned its GUID, or might this be a
copy+paste error?
Also, in the specification, the Image Decore GUID has the second opening curly
brace one byte too late, I suppose.
Regards,
Marvin.
