My old mania is, that orthodox QM solved the wave-particle dualism only in an akward way and even asymmertically and half-sidedly, on strong behalf of the particle or measurement side. I do think, this is the very reason of the inherent unfalsifyability of QM inside pure physics, its very strength, but also its main weakness, producing the famous "no-go" problems such as the notorious Measurement Problem. I myself, according to my question, would put my own vote on a symmetrycal, i.e., explicite introduction of the intermeasurement or subjective (wave) side in terms of Information Theory, i.e., by the introduction of informational observables into quantum algebras (so into formalisms which do not use the wavefunction description).
