I don't really mind it, but I don't see the purpose of it. Even if they don't want to list any names, they can still run the "Action News, Delaware Valley's leading news program" voiceover with the normal-length intro.
I wonder if they will start using the short open on ALL newscasts, at least temporarily; they'll probably find someone to replace Charlie Van Dyke, since his recent recordings have not sounded good. None of the other stations do it, either (although listing the talent seems like one of those things channel 6 will never get rid of).
