You can't guarantee that, because the parent repo can have its history
rewritten either via a forced push, or via a rebase. Obviously, this
won't happen in something like torvalds/linux.git, which is why it's
pretty safe to alternate off of that repo for us, but codeaurora.org
repos aren't always strictly-ff (e.g. because they may rebase themselves
based on what is in upstream AOSP repos) -- so objects in them may
become unreferenced and pruned away, corrupting any repos using them for
alternates.

Very good to know, thanks!
