All of the below were true:

1. Polygamy never practiced
2. Gold plates on display
3. Evidence of Jewish migration to Americas
4. Consistent first vision account
5. BoM cities, battlefields discovered
6. BoA not written

Of course what I'm really saying here is that Mormonism would be dominant today if it were true. The fact that after some 180 years it's still a largely localized sidestream religion is strong evidence of its fraudulent nature.

(sorry)
I see a conceptual point you're making, but that's about all.
this is once where I'll agree:

absence of evidence isn't evidence of absence.

Religion isn't Science

Once on the inside of ChurchCo, the gaps between Claims & Reality are tangible & current, not historic, theoretical.

Religion and science don't lie in parallel worlds. There has to be a cross-section where one supports and supplements the other. Any religion that lacks scientific evidence for its claims is very likely to be untrue.

and only if all other religions ceased to exist.
