The game developer made this great options that players can play on any map created before game. Maybe it wasn't intended to be played with ranked game, but exactly why not? Sure someone can create unbalanced maps, but other players have to agree to play on it. As opposed to standard "player build map" option that rarely creates balanced maps where player have to play on it, no agreed. Unbalance is actually in this designed nature of that option. And that is OK for BGA, but Host table option is not 
Did BGA gave any arguments for that reasoning? Did someone making this decision even read comments on this proposition? You will never know, everything was hidden. And decision was NO, just because.

PS: I don't blame the game developer, that wasn't his decision. He maybe supported it, maybe not. That was just BGA.
PS2: Why would anyone want to propose anything in that circumstances? Where they have no idea if someone even read theirs proposition?
PS3: Here is Example of map created with option that is OK. 1 player have easy access to 10 resources, other to 3. How that happened? Simple 1 player got great tiles, other not. And that kind a maps are OK for ranked games.
