Interesting modification. I suspect, since it encourages people to register an account, it is ok. However, JS review doesn't enforce policy, I believe, but exists more for security purposes and to make sure it doesn't have bad downstream effects (although, they've missed a few things that is usually seen by VE breaking).

If you do get the official green light, you should try to get the change put in Dev wiki so it can be used easily with MediaWiki:ImportJS.
