It probably makes more sense. My point is that we haven't really
thought about this and we don't define updates with no-simple
entailments in this round of SPARQL, but this decision basically fixes
the options.

I don't see having bnodes in DELETE statements with no re-use across
BGPs/template as bad, it seems nice for the lists issue and it doesn't
force a decision now on which semantics updates under non-simple
entailments will have. So I am inclined to prefer this version as
opposed to just forbidding bnodes.

Could well be, but I haven't spend much thought on that yet.
