And why Ian is it, that suddenly the Cambridge 25
Model should not be save enough anymore.
Was the safety standard proposed by the IGC not
good enough - too lax?
Is there a real reason behind this decision or is it just
a temporary mental slip if the IGC?

It was safe enough ten years ago, but now the power of PCs has increase
by a degree of magnitude and more is known about decryption software, so
it can no longer be considered 'safe'. It's called 'progress'.

In a similar way, visual observation of TPs is no longer used although
it used to be; and there is a proposal to disallow this and also the use
of Cameras, for Badge Evidence in addition to World Records.

It's called 'progress'.
