Back 2015, when the work on C++14 was still going on, it was already known that modules probably won't make into C++17. Very different situation now.

The set of ISO C++20 features is pretty much frozen after the upcoming Cologne meeting, and modules are in.

So the aforementioned death-on-arrival [1] was premature? Are there really implementations which end up faster as a result?
