Don't panic! I was unclear. You and your mirrors are clearly 3(a)
right now. So you can stop distributing whenever you want (as long as
you stop distributing both binary and source at the same time.)
I was under the impression that the focus of the request was 'how do
we reduce space usage on the mirrors', rather than 'how do we reduce
space usage on the master'. That is why I suggested that you move to
3(a) + a 3(b) notice that source would always be available from the
master server. That would reduce mirror load, but clearly not help the
master at all.
If the goal is to reduce load on the master server, then yeah... if
you just stop distributing binaries whenever you choose to stop
distributing source, you should be in the clear.
As far as source rpms for updates... I think you're right that
switching to a reliance on 3(b) would require keeping those around.
 subject to all the disclaimers I keep spewing!
 The historian in me says that would be a shame, though.
