Trinitycore has 3.4.0 for Wotlk classic but it's pure sandbox. It's so much work to be done so don't expect it to be released. https://github.com/TrinityCore/TrinityCore/tree/wotlk_classic

You can host your own WoW server locally! I would personally recommend TrinityCore. It can be a little bit of a hassle, here's a setup guide.

If they use the base TrinityCore code there's no processing (the whole point of GetAll is a minimal processing dump of the data as-is). You can see the commit for it here https://github.com/TrinityCore/TrinityCore/commit/3aaeb574050668e5a240078f6e40337c3975d110 and you can see it just dumps what is there until 55k then stops hard.

You can just compile one here - https://github.com/TrinityCore/TrinityCore

TrinityCore, AzerothCore- C++, these and others like them are the server for projects- well-known for being used on private WOW servers, so they're probably good enough for your personal project https://www.libhunt.com/r/TrinityCore - https://www.trinitycore.org/ - https://www.azerothcore.org/

There's a third option. You could try with cMaNGOS.

I suggest not downloading a repack, but rather just install it yourself. If you follow the guide 1:1 it should not be too hard I believe. https://cmangos.net/
