The downtube is mostly subjected to stretching forces. But maybe it does lose some stiffness compared to a normal bike.

Using a wire, at least, makes it less stiff in torsion since a regular «metal tube» will have bending and shear stiffness. But then, it’s a tradeoff which could be worth it for some casual bikers!
