It's almost three years since thresh was released
Can anyone recall a time where he was bad?

And so a champion needs to be trash tier at some point to be acceptable? Let's do that with velkoz then, there shouldn't be a reason with him being so balanced!
As a support main, heres what I can add to this (My opinion):

but the fact is, any primary role support (which means their first role is support) should be able to peel for their carries with more than half of their kit. For example, **Janna **has a shield that provides AD, that is not peel. That's protection, but all the rest of her abilities are oriented around peeling. Another example is Nami. All of her spells help allies escape. When you look at
there isn't much peel. Instead they offer something special in their kits. Soraka has insane sustaining abilities. Zilean can revive anyone. Taric can augment ally armor. Sona has a versatile passive allowing her to pick what she wants in different situations. These characters have one, maybe two, peeling spells. It doesn't mean they're bad champions but I don't think they really qualify to fit in the same role as

Or maybe Im just a fool XD <-------------Prob truth.
He's never been bad because of how much utility his kit is. As long as his kit remains how it is, he'll always be at the top of the support tier.
I'm pretty sure you could remove all scalings/damage from his abilities and he would still be a beast.
