Henry, in my head that was being covered by 
https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp.html#http-delete item 
4.5.2 but I see that is a MAY.
Certainly if any issue-34 proposal that included the constraint "delete of 
member requires a side effect on the container to remove the same member's 
membership triples" were to be accepted by the WG, a spec hit to 4.5.2 
would be required.  Good catch.  It's not obvious to me that we need a 
separate issue for each spec update implied/required by accepted proposals 
... I'd say let the editor-drafting and WG-review processes run their 
course until they're proven to be inadequate.

I realize this thing grew large enough to be just on the edge of 
group-consumable.  Simple answer is that I left that as something to be 
worked out later with

as an ack that your question does need to be answered.  Again, trying to 
maintain tight scope discipline in the proposal to keep it 
consumable-sized and trust that consequent questions c/would be answered 
later.  I'm reluctant to move on to those questions until we agree on the 
semantics of the terms involved at the prose level.

Best Regards, John
