Your type of coupler has become the most common one, on TTs. My 2007 Roo had the old style, like your previous trailers. My 2016 TracerAir TT has the type you're complaining about, so it's been around at least that long.
I've never had to hold it back, it just slides back and stays there.
But I unlatch it before I raise the tongue off the ball.
