We’d already had models which said that certain quantities were conserved in a system — and entanglement says that is true of certain systems with multiple particles.

To repeat myself:

Bell’s inequality is just a way to measure that correlation, ie, statistical effect — and I think it’s supporting my point the way to measure entanglement is via statistical effect.

ER=EPR is an example of a model that tries to explain what and why of entanglement.
