Not sure why we need strong duality. If we have a both a feasible point and a feasible ray of the primal then we can just start at this feasible point and follow the ray and the objective will be infinite no ?

I think the technical exception mentioned before was just about the existence of the feasible point

What about a problem like:
model = Model()
@variable(model, X[1:2, 1:2], PSD)
@constraint(model, X[1,1] == 0)
@objective(model, Min, 2 * X[1, 2])
The primal has a finite optimal primal solution with solution X = 0. But the dual is infeasible.
