Not to me, because in the software I use the thing gets actually deleted once I paste it somewhere else, not before. It's more like tagging the thing(s) for moving to a location to be disclosed later.

It could get deleted in other ways (for instance YouTube has this horrible habit of deleting your comment in progress when you finish watching a video).

I always use cut (+ immediately paste back if needed) rather than copy because it gives me the visual confirmation that the object has indeed been put in the buffer.
