So we got half of what was needed to make any kind of sense of judgement
on the patch.

And my point is that just CC'ing the relevant list for patch 4/31 is
useless. Do we need to see the whole series? No. Does everyone need to
see patch 1/31? Yes, very much so. Without that, 4/31 means nothing.

This is pretty common for tree wide changes. The relevant lists need
to see the full context, patch 4/31 by itself is useless and may as well
not be sent at this point then.
