Make full bundle list & game Id list available

I already have a userscript that uses bundle list search. I could enhance it by showing if a game is bundled in Steam search or on SteamDB for example, but that would mean from 25 to hundreds simultaneous requests to SG for each user on each search. It's not a problem for me but definitely might be a problem for SG.

Also, I have a request for extension which would hide a game on SG when it's marked as not interesting in Steam. But as SG sets it's own game Ids for some reason, I can't make it reliably right now.

What I want is 2 JSON files.
Bundle list something like this, with keys for bundled & free (blocked from giving away) games:

{
    Bundled: {
        app: {
            115320: {
                Name: "Prototype 2",
                Since: "15.02.11"
            },
            211670: {
                Name: "007™ Legends",
                Since: "15.05.09"
            }
        },
        sub: {
            38357: {
                Name: "Worms Collection",
                Since: "15.11.25"
            }
            61948: {
                Name: "3D Realms Anthology - Steam Edition",
                Since: "15.12.08"
            }
        }
    },
    Blocked: [375460,444420,287860]
}

Game Id list something like this:

{
    app: {
        423700: 633102441,
        375010: 163114315,
        469890: 1014346991
    },
    sub: {
        4323: 16255,
        94013: 695377879
    }
}

Of course, the structure is up to devs.
With these lists available I'll be able to load them once on extension start & keep them until user closes all Steam pages, or even store them locally & check for updates like once a day.
