You couldn't pay me to keep a 20" "salmon".....

That’s fine, hopefully you will be done for the day after hooking your two wether they meet your standards or not. You would be in favor of everyone else keeping them and going home right? Or do you want them sore mouthing fish and trolling till dark?

Keeping the first two would definitely support the use of fishing larger gear, to Target the bigger fish that everyone seeks.
It kills me when guys fish small lures like coho killers, and then brag about the one they caught after releasing 20 sub legals.

To me, it's no different than hooking and killing several legals, because those sub legals are tomorrow's trophies.

Anybody else old enough to remember the days when the lower size limit on all salmon was 16"? Three fish limits then, too, so you kept any fish that was likely to die if released.

In the 70's there was, I believe, no minimum size in SW. That changed, I believe, in early '76.
