I have to admit, I am no longer nearly as concerned as I used to be about whether I have a "permanent" version of content. I already have a house full of stuff, and more gaming content than I can really use in my lifetime.
More importantly, it isn't like I'm going to re-use gaming content a whole lot. I ran Lost Mine of Phandelver once. Had a bunch of fun with it. Never touched it again. I ran The Wild Beyond the Witchlight - same. Don't expect to ever touch it again. I don't expect to need Harengon stats ever again. Played Dragon of Icespire Peak. Played Rime of the Frostmaiden. Don't expect to ever see those again, either. I don't expect to play characters of the same classes any time soon.
So, I'm not really worried if the DDB version isn't separate - if I'm using it in DDB once, that's probably the only time I am using it.
