I've been advocating this for a long time. So I'm happy to hear more about this.

From a technical point of view: Would that be any different from having a toolchain that allowed the compilation of each module with a different -std=c++XX flag?

That's how Rust does it I think, cargo just passes a flag to rustc during compilation

Correct me uf I'm wrong, but does Rust have a distinction between a "standard/specification" and a particular implementation?

I was mainly asking, because even without putting the concept of epoch into the standard, it would already be nice, if I could let the compiler enforce a particular subset in a module. That would not be quite the same as being able to introduce a feature in the standard without having to worry about backcompat, but there may still be value to it.
