I'm a git noob, so I'm sorry if this sounds dumb but wouldn't

git clone --single-branch

achieve the same thing (i.e, check out only the branch you want to build) ?

Also, why would you not only check out one branch when doing CI ?

hmm, the --depth implies single-branch, but the +refs overrode it by making sure it had the data to match all branches because of the wildcard refspec ?
