“Is there a reason they shouldn’t all be part of a user’s Library?”
For me there is: Clutter! I have no interest in most of the things in this bundle - which shouldn’t come as a big surprise for a bundle of this extremely generous magnitude. I currently have no use for the asset packs, the Unity games, the vast majority of the TTRPGs, things that have only a single screenshot… And I’m already at the point where I’m collecting links to ask itch.io’s support team to remove those entries from my library again. Right now some users are complaining that they don’t have everything they legally own marked as “theirs” - and I get that, I really do: Before I think “Should I buy this game?” my first thought is “Do I already own that game?” and than I cave to copy the name and paste it into the bundle’s search box. But: It would be far more inconvenient for me to navigate almost two thousand things - in a similar fashion I would have to navigate the bundle, I’d like to point out.
And that’s the reason that I don’t chime in and repeatedly ask for a feature that the admin(s?) already know the demand about. Don’t get me wrong: Always fight for the things you believe in! I’m just offering a different point of view. I’m not against there being an option to claim all those game - but I can foresee the flood of requests for an “undo”-button as well…
