A word of caution: EASA are masters at safeguarding their gravy train - just like every other EU agency.
This was less than 3 years ago but had zero effect as far as anybody can tell. Mr Kazatsay was later seen sitting on some EASA committee... it didn't take him long to go native. Perhaps EASA gave him a honorary JAA IR

A JAA IR seems to work pretty well to achieve that objective

(didn't work on me).
If some politician tells EASA to back off stupid regulations, all that EASA has to do is sit tight for a bit and the said politician will move on. They always do. The incumbents always win.
Not all EASA regs are stupid. A lot of their proposals are sensible, but none of them have yet been implemented - usually because (a) political resistance from established interests and (b) EASA having taken on far more than they handle. Well,
one was: the grandfathering of national certification (mod approvals) to be pan-EU. That was a few years ago.
Everything else EASA has
delivered to date has been a total waste of time and money.
Screwing the N-reg community
before delivering a straight conversion route was spectacularly stupid, but it was done to beat the USA over the head. It was a 100% politically motivated stunt; a private project run by about 5 people there.
In Europe, France is the only country with a backbone. As well as double jointed shoulders
