Everything JAFO said except I havn't finished it yet. At the age of 66 I have no future as an ATPL to consider, Medical I might manage, but how long for? Foreign touring, I'd rather see our bit of the planet first, The "this may change" cliche by NPPL committee seems plausible / encouraging, esp with regard to seaplane rating difference training.
All in all a good thing for a fair chunk of UK GA.
One can always upgrade if required or possible.
