You tell me how you would decide who should know? Using what criteria?
There are plenty of archaeologists (and a sculptor) on Britarch that would like to have been able to see it for further research. I'd just like to be able to see it. And if as happens these secrets never stay secret, what happens if (as Mr Redfern fears) we see it being sold on eBay??
It now doesn't even seem very secure, let alone safe from deteriorating as is feared by some.
