I love that two of the comments presume that this change is recent and both for different reasons. It's as if most people don't know the current state of affairs unless it hits them with a hammer on the face.

I personally didn't know this, but I also don't submit PRs on github since a while ago.

I imagine in order to really notice this in the course of your routine, you'd usually be either maintaining open source repos (exposed to the vast amounts of AI-driven PRs), or submitting PRs to open source regularly.
