Sporting legislation for seasons, weapons, game management etc is largely centered around opportunities. That's why here in Ohio you can hunt deer with shotguns, handguns, centerfire rifles, flintlocks, percussion locks, in-lines, crossbows, compound bows, recurves, longbows and probably something I've missed. Seasons for youth are old news. Late muzzleloader season forever. It's all designed to put more people in the field yearly, generate money (many directions), manage the deer herd, and keep the train rolling ahead.
I don't see a ghost of a chance for a traditional archery big game season here, or ever restricting the higher technology weapons so long as there is adequate game statewide. Even if the game numbers decline, I believe the state(s) will simply make a myriad of other choices and adjustments as opposed to removing or severely restricting a class of weapons. Primitive weapons seasons once filled a large gap of time, mainly because their success rates were very low. Those time gaps don't exist here anymore...you can hunt deer from late September until early February with more weapons than Fort Knox.
I also cringe to think what a traditional-only season would look like here. Trust me...guys would figure ways to make it (and us) look like the world's worst bowhunters are carrying stickbows. There wouldn't be anything traditional about it. Guys would be stuffing their plastic quivers with mech heads and basically using every last piece of tech possible to help them manage a $179 recurve bought at Dick's Sporting Goods.
You can't legislate ethics, desire, lifestyle or commitment...what we have.
