Replying to Swapping skis between feet

I've always been told that you're supposed to always be swapping your skis between your feet to keeps the edges in good condition but I think most people don't. If you already detune your edges how much of a difference does it make? What side of the edge wears out, is it the inside edge of both skis or the left or right on both? I always switch them because my skis don't have a super obvious right and left graphic and I don't even notice when I put them down, but if you were riding something like Jets you would look stupid as hell having them on the wrong feet

tldr will park skis start to feel weird if you always ride them on the same feet
