In this old thread [1] one of the Azul developers outlines a potential path to having a C4 type GC for Go. Interestingly he mentions moving to a generational collector first, before moving to concurrent. It seems the Go developers have decided to go the other way, i.e. make the collector concurrent, but not generational. One of the reasons given for going generational first is implementing a write-barrier, but from the blog post it sounds like that is implemented for this concurrent collector anyway, so maybe it doesn't really matter.
