--raw-except=web allows using yt-dlp but not any other special remotes. Currently this option can only be used once, trying to use it repeatedly will make option parsing fail. Perhaps it ought to support being used more than once, but it seemed like an unlikely use case to need that. Note that getParsed is called repeatedly when the option is used with several urls. While implementing DeferredParseClass would avoid that innefficiency, it didn't seem worth the added boilerplate since getParsed only calls byNameWithUUID which does minimal work.
