This is probably going to save quadrillions of CPU cycles by making an untold number of deployed Go applications a bit more CPU efficient. Since Go is the "lingua franca" of containers, many ops people assume the Go runtime is container-aware - it's not (well not in any released version, yet).

If they'd now also make the GC respect memory cgroup limits (i.e. automatic GOMEMLIMIT), we'd probably be freeing up a couple petabytes of memory across the globe.

Java has been doing these things for a while, even OpenJDK 8 has had those patches since probably before covid.
