So....
If I am a warpriest with the sun blessing,
And I successfully identify that the spell my enemy is casting is summon monster IV
and I use my minor blessing power to Blind him for 1 turn, is he unfazed while he is casting?
However, if My buddy buddy Evil Cleric, casts blindness, effectively blinding the person using summon monster IV,
Then he has to make a concentration check?
That is correct. I really do think it should have been a rule, but it isn't.
There are quite a few areas where the rules don't really make sense in my opinion so I'm not really too shocked about this.

I realize that, but the book specifically calling out spells, and not SU's as causing concentration checks, not having a formula for it still means that your formula, just like the one I presented earlier are still not official. They are both just suggestions.
Correct. There is no specific guideline for this situation. (although I contend that what it should be is obvious, and I am very confident that if Piazo were to ever address the question directly that it exactly what they would say).
What is incorrect is the concept that the existence of a list of specific DCs for a GMs convenience is automatically exhaustive and that anything not on that list cannot, or should not, apply.
There are quite a few times in the game where the GM has to determine something without a precise formula to do so. A GM doing that is part of the rules, not a house rule although codifying it for future consistency might sort of be considered one.
One thing to realize is that even for the clearly defined DC of the concentration check of a spell affecting a caster there is still going to be GM calls and some table variation because when to apply this check isn't specifically and clearly defined only given as "If the spell interferes with you or distracts you in some other way." Some GMs might consider blinding being interfering or distracting, some might not (I would). Some might consider a roar from ghost sound being distracting (I would not). Making this choice one way or the other isn't precisely a house rule, but it is a GM call.
