// This class is misnamed. Conceptually, this class owns features which are
// scoped to the entire process. The features must span multiple profiles. If a
// feature is scoped to a single profile it should instead be added as a
// BrowserContextKeyedServiceFactory.
//
// Historically, members of this class were lazily instantiated. Furthermore,
// some members would not be created in tests, resulting in production code
// adding nullptr checks to make tests pass. This is an anti-pattern and should
// be avoided. This is not making a statement about lazy initialization (e.g.
// performing non-trivial setup). This is about having precise lifetime
// semantics.
//
// New members should be added to GlobalFeatures, and be unconditionally
// instantiated.
