It'll help whenever rounds are sticking. So it works for every kind of mag. I used a metal scraper, but probably 600 grit is fine. But if there is not a feed problem, leave it alone.

Use a medium India stone, they are cheap, and available in several sizes & shapes from any machine shop supply, like MSC, and McMaster-Carr.
I have a good selection of 4" & 6" long, 1/4" through 1" cross section stones in round, square, and triangular shaped.
Don't drop them, and keep them oiled, and they will last decades. Some of mine date back to the '70s.

I don't think it would hurt anything to ease the edges a little bit if you feel the need though. Aside from not scratching your brass when it feeds (is this even a concern?) I'm not sure what real benefit there is in doing this.

I reload my Berdan steel and brass cases, so if I can limit the abuse on the cases, it's a positive for me.

Don't reload, I gotta agree with you.

I don't recall any of my x39 brass getting noticeably scratched back when I was reloading this caliber. Perhaps i was fortunate that the Hungarian and EG mags I was using didn't have burrs on the feed lips. I lost more brass out in the weeds than from damage.

Its the KCI ones that are very sharp. I'll probably just file a small or very small amount.
