I think that makes it much clearer, and quite correctly, whilst at this stage people are bound to speculate it will only be when an interim report is published that speculation will have a focus.
As you rightly say, departure from cruise flight is not the norm, and the manufacturer (historically) will be anxious to have that interim report published.
At that point some informed opinion might be helpful, meantime, these threads just go around in ever decreasing circles with every man and his dog pushing their pet theory, this was not always the case, but seems to be the modus operandi now.
