*Must* was the wrong word. 

I meant that a standard core that they agree upon that gives some kind of base from which to work, a minimum level. I read @reggaemuffin's proposal but for the average user (myself included) it is going to be very difficult to get the head around without expert understanding let alone if there are 50 variations versions floating around in posts lost to time etc. 

So will there be a proposal put forward that can be tweaked by discussion to reach some standard form that a witness can agree to and then we as community can vote accordingly based on at least that base level of standardization. And then the possibility to see clearly which witnesses agreed to it and which didn't? 

It is already difficult to know what all the witnesses are working on etc so having some way to know that there is at least a base level met would make things somewhat easier to track for less technical users who don't live 24/7 on Steem or in the processes of software development. 

Of course, it is up to the community to develop the interfaces, the understanding  and our responsibility to keep track of the 200+ witnesses and their comings and goings each day but it might be easier with a tool or two.
