As I've written elsewhere in the thread, having worked at a large Enterprise in collaboration with Legal, if there isn't tracking of what AI contributions you have, it's harder to be protected legally by ie Microsoft's indemnity clause if you're sued

It's definitely helpful to know whether a PR was AI-assisted or not and the git attribution line is a simple and effective way of communicating that.

I also recommend specifying model name and version so the maintainer knows upfront the level of slop they are dealing with.
