P1881 Epochs proposed to WG21 (the C++ standards committee) in 2019 by Vittorio Romeo

The committee found plenty of problems with this, and made it clear that if Vittorio did all the hard work to resolve those problems they would find more, P1881 was abandoned.

There was a Reddit thread https://www.reddit.com/r/cpp/comments/1tja9zr/c_profiles_a_c... which suggested that the "Profiles" idea Bjarne is pushing for C++ 29 could be used to deliver this.

So, you're not the first person to notice that this is a good idea, P1881 was written after Rust's 2018 Edition, but before 2021 Edition with its even more significant improvements. I firmly believe Rust's Editions unlock not only technical possibilities (though it does certainly do that) it unlocks an appetite from users which is good for your ecosystem.
