This has two benefits: First, we ensure that the main branch works even if the runners/dependencies update. Second, GitHub's caches are scoped. They only work among commits of the same branch, except from the default branch. (https://github.com/actions/cache#cache-scopes) Therefore, if we ensure that the main branch is always cached, we should always hit the caches and have quick turnaround times on all our branches and PRs.
