How do you figure it will never come back? The CPW added this as an additional season back in 2014 and hunters didn't take advantage of it so they made a management decision that it wasn't needed because the harvest hasn't change year after year even with the April season. The CPW adds and subtracts Deer, Elk and Antelope licenses all the time it's Herd Management it's what they get paid for.
If hunters want to make it look like Mountain Lion hunting is needed then they need to go out and buy a license and participate. There is about 2500 Lion licenses sold every year, that's it. With what's on the horizon with the mountain lion hunting ban going to the ballot box I feel every hunter even if you hunt with the license or not should buy a mountain lion license this year. Show that it brings in money. The only way these things go away forever is thru the Legislative process, examples spring bear hunting, trapping, wolf reintroduction.
