    # We want our compiler cache to always update to the newest state.
    # The best way for us to achieve this is to **always** update the cache after every landed commit.
    # That way it will closely follow our development.
    # And if a PR diverges a lot with its cache that's not a big deal, as it will be merged eventually.
    #
    # This is a workaround for the fact that GH doesn't support updating existing caches.
