In the future, we would like to add a few injected dependencies of ProjectConfig. The fact that we can't use an assisted factory will hopefully prevent us from adding too many. Regardless, it's reasonable to group together the few "read" static constructor method into a single class along with the bare create method. Change-Id: I391ae8e37086c22c10e7f342d46e08dd2242df71
