Should I move enchanted items to a cleared level so that monsters can't get them?

I'm playing Dungeon Crawl Stone Soup. I'm on level 10 of the main dungeon.

When I kill an orc, it may drop, say, shiny plate mail and a glowing battleaxe. If I leave those items on the floor, an enemy—say, an orc warrior—could later pick them up and use them.

Should I trouble myself to move these enchanted items to a cleared level? If not, why not?
