Moved to a 4:3 format. This would have allowed for smaller, higher
quality lenses than are needed to support an APS 3:2 format since a
4:3 format occupying the same sensor area would be less wide, putting
less pressure on the lens design to support such a width. Plus, it
would have made more sense because most 3:2 images end up cropped at
the sides for 70% of their applications anyway. That extra side waste
has made it much more difficult and expensive for Sony (and then Nikon
and Canon) to do mirror-less systems which has/will result in poorer
quality lenses overall. Time to ditch the ancient film format.

What issue would that be? What Sony lens (E Mount, I assume) do you own?

For lens designers, the easiest (ideal) format is 1:1.
