Comment:
You mean instead of pulling in and extracting the distfile? Should be possible, yeah. Is there a policy on this, when do we do cloning instead of extracting a checkout? Last time that topic come up, [the response was](https://github.com/void-linux/void-packages/pull/35082#issuecomment-1015415324):

In that case it would've been for generating the changelog, which would be done every time, so I didn't end up doing it, isolating it into the check stage that isn't automatically executed here made sense to me.
