I think it will be true because raa are under pressure from casa to lift their game after all the drama a while back.
It actually makes some sense.
If you have taildragger endorsement but buy a nose wheel and do all your flying in that then how can raa be sure that you can handle a taildragger if you haven't been flying one for the last 2 years .
You will have to decide what endorsement you want to keep it do the bfr for both .
