Huge problem with the recent update

The new change for "need redstone"- Commandblocks is a very bad decision in my opinion. There are many developers, who spend really much time in creating things with Commandblock, for example me... Ive been working for the past two years on a huge server with only commandblocks. I was already done, until the new change. I talked to other "Commandblock-Creators", if i made any mistake, or if they have the same problem. All of them agreed to me, that everything they created is broken. One of my friends realized that in the change logs, there is said, that "Need-redstone" command blocks have been changed... Every single commandblock creator thinks, that this change is very useless and just throws months and years of work by developers away. I think, i can speak for every command-block creator, that we want the old way back, how these type of command-blocks work..
