On the contrary: an accidental leakage is one of the many reasons a VPN provider cannot be trusted. Say I want to hide myself temporarily - which is safer - a VPN provider, having no idea how they handle data, logs and whatnot, or a tiny vps somewhere for half an hour while you need it, get your job done and then nuke it out of existence. The latter would be infinitely harder to compromise if you know what you are doing as opposed to a service that is running 24/7 and having no idea how data is retained.
