Sadly, it ain't a matter of whether speed skating section has any thoughts of leaving being advantageous or not. Speed skating has glommed onto and stuck like glue to figure skating. The co-opting is so cemented, that figure skating entity don't even know how to think for themselves. They've been controlled for so long!
When one rebellious, enterprising leader of figure skating attempted to rally a revolutionary split, in 2003, the attempt failed miserably. It was not well-planned because there was not enough strategic foresight, nor solid support, but it was a brave effort. The rebellion's leader and courageous visionary, Ron Pfenning of the U.S., was thanklessly voted out and banned from further participation in the sport. The soft support for separating crumbled completely, as all the figure skating members fell back into their weak, fearful, secondary roles.
Figure skating entity has always been viewed by speed skating entity as the lesser than sport, but also as speed skating's personal cash cow that can never split away to find freedom and autonomy.
It's mostly been advantageous for speed skating to infinitely control and hold on to figure skating. Not the other way round.
