MD put in a similar rule a few years back, only 1 bass over 15". It only applies to our tidal waters (where vast majority of bass tournaments are), only applies between June and October, and specifically and only applies to tournaments. You can get a waiver for a normal limit as long as your tournament follows basic fish care protocols (which 99% of tournaments already do).
It's frustrating becasue it really just amounts to another hoop to jump through in order to hold a tournament from a MD ramp (on the Potomac we can just launch on the VA side and avoid it)....
It's more frustrating because as you think about it, you realize that you and 20 of your buddies can go out and catch 5 big bass each, keep and then kill/eat them perfectly within the MD regulations. But if you and those same 20 friends go catch those same 5 fish limits each, but weigh them for a tournament and release them alive? Nope, illegal unless you file all the paperwork and get permission from DNR. It's silly.
At the end of the day, its not that big of a deal since the waivers are accessible, hopefully it will be that way for OK anglers too.
On a related note...I went to several of the public meetings that were held when this rule was implemented to oppose it. While there we heard from the DNR biologists on the reasoning for this rule and unfortunately bass fisherman shot themselves in the foot (at least here in MD). DNR went to observe local tournament weigh-ins and said that they observed poor fish care - Noting that bass were frequently put in bags without water, kept out of the water too long, dropped and/or put on the pavement, and that a lot of these local clubs had zero organization to their weigh in process. Obviously these groups are the exception to the rule, but DNR observed this stuff and felt the need to force tournaments to adhere to basic fish care. We need to police ourselves, if you are part of tournament trail you need to preach fish care to your members and if you observe poor fish care in your ranks you need to speak up and correct it. In my club, we'll hammer any member we see doing something boneheaded regarding fish care - Wish more clubs would do that.
