Statements like that are what make me nervous, because you seem to be saying we know exotic dark matter is out there and are now simply refining our understanding of that known substance. Another unhypothesized approach might be accurate, but we've already found the answer so we won't bother looking for it. If you're just saying direct detection experiments will narrow the space of all possible theories that's different, of course, but if you're saying dark matter has been proven by default and we're just seeking experimental and observational evidence to better describe what we know to exist we're back where we started: We've never directly detected it, but we know it's there, so let's keep looking till we find it. Whether it actually IS there or not. I'm not confident that we'll quickly realize if it's not there because it's impossible to prove a negative; that's why there are still people looking for proton decay despite the fact it's not only unlikely to occur, but unlikely to be detectable in any reproducable way even if it does.
The evidence we have points very strongly toward dark matter being exotic. (This is what, the dozenth time I've said this?) That means that most physicists are going to focus on those avenues. Some physicists will continue to focus on other avenues. This is how research works in any field.
Your problem seems to be that you're tossing around these qualitative "worries" without any quantitative analysis. When you do this, every concern seems like it's all or nothing; this is virtually never actually the case. The repeated comparisons to proton decay (a subject actively researched by only a handful of people) demonstrate how divorced your worrying is from quantitative reality.

I still think dark matter's just non-luminous matter without a convenient light source to reflect.

We've just about ruled out the idea that dark matter is just non-luminous "ordinary" matter.
