Many of the contributions for the ports aren't from the Go team themselves, but from external contributors. Also, work is in progress to improve build times, although I don't know if that's an active focus, rather than just something that's being fixed as time permits. A few improvements have already gone back to the current development gate for a variety of cases. I think it's important to remember that development can be done in parallel, just because you see work being done on an area that isn't important to you doesn't mean that there isn't work being done on the area that's important to you as well. Some of these changes take a long time.
