Usage ping for epics_deepest_relationship_level should not be 1 for most non-EEU cases

I was looking into the usage ping data.

I saw a lot of non-EEU usage pings have that have epics_deepest_relationship_level=1, when I think it should be null.

If your instance has never had epics before, this value should be null. If your instance had epics before (but no longer have access because you lost your license), you should probably still send some number because epics are in the database and it's probably 1 or greater.
