I doubt it will reduce all that much. It’s still really convenient and it’s way more difficult to write and use a source generator than it is to just use reflection. Source generators will get used for stuff that really benefits from the extra safety and from the increased performance, but that still leaves many use cases for reflection.
I see most foundational libraries doing the effort to move to source generators everywhere possible. It's a big multiplier. Then it's up to the applications authors to choose if they care or not about AOT.
