It's right that remains found by chance should be given the right treatment, and if possible identified. But going out looking for them by scientific means sounds a bit like grandstanding for attention, and there is something a bit distasteful in the idea that relatives should still need release. These men died in a war that was almost universally believed was right and proper, and I don't believe anybody needs more release than that, unless some fast-talking stranger comes and convinces him he has a problem.
There are parts of northern France where the task would be a lot easier, since there are more unknown Allied soldiers buried than French civilians since the beginning of the world. But it was an honourable condition, which their families understood. Even nowadays, they chisel an occasional name off the Menin Gate memorial to the missing. But it doesn't need more than that.
