Instead of using the 'subscription' type, you add items to the list with
type='group' for each group in your roster. (Or use type='jid' if these
roster items are exceptions).

Obviously, the source of the difficulty here is that jabber:iq:privacy
treats subscription='none' the same as 'not on my roster'.

If you really think this is a serious problem in the wild (I'm not sure
it is), then we could propose fifth subscription value (e.g. 'unknown')
for jabber:iq:privacy in RFC 3921bis.
