Say we have all the empirical evidence from 19th-century science prior to the observation of the wavelike diffraction of matter particles, plus 21st-century math and theory to construct an alternative explanation.

To explain any macroscopic effects that necessarily depend on matter waves. If there are any. Which is my question.
Superconductors and Bose-Einstein condensates are both macroscopic phenomena that result from coherent matter waves.
Maybe there aren’t any in our conceptual universe.
