We've been mixing vocals and voices in stereo since forever and that was never a problem for clarity. The whole point of the center channel is to avoid the phantom center channel collapse that happens on stereo content when listening off center. It is purely an imaging problem, not a clarity one.
Also, in consumer setups with a center channel speaker it is rather common for it to have a botched speaker design and be of a much poorer quality than the front speakers and actually have a deleterious effect to dialog clarity.
It's a clarity problem too. Stereo speakers always have comb filtering because of the different path lengths from each ear to the two speakers. It's mitigated somewhat by room reflections (ideally diffuse reflections), but the only way to avoid it entirely is by using headphones.
Try listening to some mono pink noise on a stereo loudspeaker setup, first hard-panned to a single speaker, and then centered. The effect is especially obvious when you move your head.
Welp we had no issues in ye ol days. When DVD releases were expected to be played on crappy TVs. Now everything is a theatre mix with 7.1 or atmos and whatnot.
Yes we know how to mix for stereo. But do we still pay attention to how we do?
