  2. generally, if there is a liquid and solid, we term the solid the solute, and the liquid the solvent.

    If in an alloy, we use the term solute for the minor component.

    Now in the case of miscible materials, there is no rule when the proportions are approximatly equal, as you point out, it makes not much sense.
