alt+dragging creating a copy makes sense with the legacy text editor clips, and the older dynamic link template files where you'd change the text in the Effect Controls. Newer templates don't need it, however.
Changing the behavior completely would make working with older projects slightly more cumbersome, but it'd be nice if there was a way to toggle the behavior on/off or have two kinds of key combinations, like alt+drag for replace and alt+shift+drag for copy and replace.
