After suitable review (nature of the engine failure, performance, etc) the crew made the decision to land above max landing weight.
All ended well, aircraft checked out for overweight landing, nothing adverse found
as a result of the landing but the engine was a mess.
Company completely supportive of crew actions/decisions.
In fairness, with the jettison system inop, they didn't really have much of a choice, now did they?
To add to the debate, what does the MEL say about having the jettison system inop? That may give some insight into what Boeing thinks.
Disclaimer- I've never flown an airplane capable of dumping fuel.
