There is no safe way for Go code to ever see these structures, so the difference should not matter to any ordinary Go programs. At this point I don't think there is any deep reason for the slightly different design. Historically it was because the gc implementation used a runtime cache, but these days the gofrontend implementation used by GoLLVM also uses a runtime cache.
