[1] In Chromium terminology, "Root Cache Path" (CefSettings.root_cache_path) is the "User Data Directory" and "Cache Path" (CefSettings.cache_path) is the "Profile Path". An empty "Cache Path" value means that the browser is using an Incognito Profile. Even in Incognito mode, some per-installation data will still be written to the "Root Cache Path" directory.

[2] Chromium's process singleton lock protects against multiple app instances writing to the same "Root Cache Path" directory. Implement CefBrowserProcessHandler:: OnAlreadyRunningAppRelaunch to handle the case of app relaunch with the same directory.
