I did see some depth=1 or something like that to get only a certain depth of git commits but thats about it.

Yeah, that’s a shallow clone. That reduces what it pulls down, and I did try that (you most-likely want a bit more, probably to also ask to only pull down data from a single branch) but back when I was crashing into it, that wasn’t enough for the Cataclysm repo.

It looks like it’s fixed as of early this year; I updated my comment above.
