Well, mirrorless cameras make differences in coverglass optical path length way more obvious. Can't stop addressing the elephant in the room on the L-mount, where Leica and Panasonic just took vastly different approaches. The actual mount may be the same, but the optical path is not. Some lenses may behave vastly different on different cameras, some - less so...
You just can't have too many lenses...
