This seems to imply a need for GPL4: its purpose would be to infect code that was written by a bot that learned from GPL4 code. Otherwise this can be used to circumvent all except the most lenient free software licences.

I would say that GPL3 already probably does that, which means that nobody should be using this for actual code (except if it's GPL3). But it might be helpful to be explicit about this.
