I haven't been following closely the state of StandaloneMmPkg on edk2 - as we
were ready to sync up some of our earlier MM stuff to edk2 I learned that the
support in place is only partial as patches have been coming in slowly so we
chose to implement a version based on the early joint prototype work we did
("uefiproto" repo). In this there is a DXE component that produces the SMM
Communication protocol and also ensures that when key GUIDed events occur in
DXE that they are forwarded to MM including EndOfDxe.
I don't see a strong argument for not forwarding the event signaling
information to MM - MM can either use the information or ignore it as it sees
fit. I can see scenarios around variable services where knowing what phase of
boot the normal world is in is necessary.
