I don't think that's a rule. SMM is used where it is needed.

This is obvious. The conclusion you can draw is that these boards do
not need SMM.

This is not accurate. Note that there is an automated build system
which build tests all boards on each commit, and at the moment all
boards build without errors.

Why are you so interested in SMM?
As I mentioned above, coreboot will avoid using SMM unless it is a
requirement for a particular platform.
If you want to add SMM to a platform where it is not used currently
(and thus not required for coreboot) then it seems that you you have
a lot of research and development ahead of you.
