Your non-lousy product stewardship would let me replace the video file of a John Carmack tech talk with an Amway recruiting video?
This is a very useful feature for people since it would give creators the ability to fix errors in their videos without creating the confusion that happens when creators try to do this currently.
Every single time when I saw a reupload it had tons of comments saying something to the effect of "Didn't I see this before?" or "Didn't you upload this Yesterday?" and the creator commenting X times: "Sorry it is a reupload to fix Audio/Editing/Facts"
Can you then replace a John Carmack tech talk with a Amway recruiting video? Yes, but there was nothing stopping you right now from uploading that Amway video and simply calling it "John Carmack tech talk" anyways.
Both are minor things, but I am in favor of creators being in control over their videos. Especially since it would get used to correct accidental misinformation and things like that.
I just don't see much harm in the ability even if the video creator could completely switch content.
