I think the narrower use is better, though I'd say things like Makeruna Wasshoi! should qualify too--the online version is the same as the physical version, but it was available digitally months sooner.

I've seen it used some apparently in that broader way, but that doesn't seem very useful when almost everything from acts active after a certain year would be included. Really if something isn't released digitally anymore it might be trivia-worthy.
