Question: check for unsaved changes in session

[drakhart]

This is just a question, not a real issue: while using this library I came up with the idea of calling session.saveChanges() automatically before sending the server response (we're talking API here) whenever the session has unsaved/pending changes, but I couldn't find any way for checking for this (I inspected some session objects at different stages).

So, is there any publicly accessible way to check if a session has currently unsaved changes?

            const newSession = store.openSession();
            const basicName = new BasicName();
            basicName.name = "Toli";
            await newSession.store(basicName, "users/1");

            assert.strictEqual(Object.keys(newSession.advanced.whatChanged()).length, 1);
            await newSession.saveChanges();
