I'm still going to discourage godly, or goddessly, intervention. Leave the humans alone, they are not of Faust. You don't see me making groups of Supremes guarding the Triarians or the humans, and accelerating growth and expansion. They are among the humans, yes, but not trying to influence them. Just living, monitering. 

And saying "Hun" is a very feminine gesture. Broaden your horizons in terms of words, but language is sexist, you know.

And the Supremes will always look down on Equestrians. They openly defied them repeatedly when, especially in their own eyes, they were trying to assist and insure the Equestrians, after they had spread distrust against themselves. The Supremes see it as reaching a helping hand out, and both the people, err, ponies that had fallen down suddenly mimic and blindly follow their corrupted guide, Faust, and beat the helping hand away with a stick. 

And don't say the Supremes are stupid; as an eternal species, half god, they each would be aware of Faust, and through her constant activity, Equestrians. They would see the 'alternate' and 'parallel' universes where the Equestrians, for some reason, believe peace is upheld and maintained with overwhelming military power, and that this is one of several attempts to have her perfect Equestrians.

So they would look down on them for being just another test, repeated after constant failure, because they are Fausts' creation, among other things. 
The Equestrians have earned their place in the Supremes' minds. They will do their best to stop a close alliance from any of the bigger groups with the Equestrians. Memory transfer isn't out of the question, either
