Correct, that is (and always has been) the present setting. Only one dragon egg can be in the world at once. Any existing eggs explode and destroy attached machinery.
If you have such an egg and such machinery using it, I strongly recommend you give the egg a bit of space asap because there is a strong chance it will be exploding tonight. I realise this is not much of a warning but this is the consequence of using dangerous items. I am not sure of the blast radius but I suspect it is small.
