Hello Anthony,

If the MdeModulePkg maintainers are ok with this, then I'm fine with it as well.

I would like to suggest to include a patch that does

diff --git a/MdeModulePkg/Universal/SerialDxe/SerialDxe.inf
b/MdeModulePkg/Universal/SerialDxe/SerialDxe.inf
index 81066a26a278..761c2e6649de 100644
--- a/MdeModulePkg/Universal/SerialDxe/SerialDxe.inf
+++ b/MdeModulePkg/Universal/SerialDxe/SerialDxe.inf
@@ -11,7 +11,7 @@
   INF_VERSION                    = 0x00010005
   BASE_NAME                      = SerialDxe
   MODULE_UNI_FILE                = SerialDxe.uni
-  FILE_GUID                      = D3987D4B-971A-435F-8CAF-4967EB627241
+  FILE_GUID                      =
D3987D4B-971A-435F-8CAF-4967EB627241 # SERIAL_DXE_FILE_GUID
   MODULE_TYPE                    = DXE_DRIVER
   VERSION_STRING                 = 1.0

so that it is clear for future users that there is a symbolic GUID
constant they can use.
