I don't understand how this is supposed to be implemented into the current system. Not all maps would support the game mode, so it means we would need another section exclusively for the maps that do. A scenario that will just lead to clutter and/or confusion in my opinion.
And what's with the sudden desire to have neutrals clogging up a map? I think it's a rather ridiculous concept since neutrals have a tendancy to hinder gameplay, not improve it. I can only see this sort of thing ending up in build up games, because A) people don't want to take on neutrals until they have large numbers to do so or B) they can't get through all the neutrals because of bad luck with the dice.
Regardless of whether it is implemented or not, I think it would be a very small minority of maps that would use the feature and thus think it's a bit pointless. Just my opinion.
