I'm not sure where we disagree about the above. This is a call for scientific interest in the issue not proof and understanding of anything.
What are you suggesting science has no interest in? Science can be (and is) used to address literally any phenomena or question. The "prejudice" against "the paranormal" isn't about the kind of phenomena lumped under the term (which as we've covered, varies anyway), it is about the approaches proponents take to that category of phenomena. As I've said, all sorts of things generally considered "paranormal" (or that once were) are routinely formally studied using scientific method, sometimes even in direct response to the claims of "paranormal" proponents.
I agree with that also. But with the vast majority of the universe not directly detectable by current physical senses and instruments a breakthrough may not occur until next century or whenever.
So? That doesn't change anything I'm saying. There is a fundamental difference between "we can't yet detect" or even "we never will detect" and "it cannot be detected".
It is a valid part of the scientific mindset to propose theories in the face of a 'we don't know' situation. That is all I am doing here.
You're really not. You're not presenting any well formed hypotheses or theories for anything and what you are presenting is couched within the default assumption that whatever you're proposing can't be directly studied (you literally quoted a definition of "psi" that declared it "...
cannot be explained by traditional scientific principles."). If something can't be detected, you can't apply scientific method to it (but then you can't claim anyone has observed or been aware of it in any way either).
Anyway, this isn't about you, it's about the general concept of "the paranormal" and all of the people who promote it. You are far from the worst example of the reasons for the "prejudice" the OP is referring to. The concept itself remains essentially meaningless and counter-productive. I you want to study particular phenomena, just do that. You don't need to raise anything about "the paranormal" at all.
