  Recently, Wang with Stankiewicz (Phys. Lett. B 800 (2020) 135106) opposed the
widespread belief that due to quantization, the Big Bang singularity {\em must}
necessarily get smeared and replaced by a non-singular "Big Bounce" process.
Their claim is supported in a methodically independent manner in which just a
highly schematic model (viz., the discrete and drastically simplified
Wheeler-DeWitt equation) is considered. Our comparatively elementary
argumentation is constructive, based on the assumption that the evolution of
the Universe can fully consistently be described using an innovative, hiddenly
Hermitian version of quantum theory formulated in a properly upgraded Dirac's
interaction picture.
