I'm quite sure that Elon has mentioned on twitter that the Founders Series Roadsters will come with the SpaceX package but I wasn't able to find the tweet. I was able to find the thread where he talks about the package in general, however.

He was talking about a 2020 edition not the 2025 edition.
"Is the Spacex package included on founders series? Fingers crossed for my founders 2020 roadster to include it!"
