Wouldn't it be easier to just leave the Resource Production (RP) ban in place everywhere and not worry about it? It's effective and very powerful on medium maps and skirmishes. On huge maps, it might work if you have 10 cities with full resource purchases – you kill someone in your main city (if you're a Necromancer, that's +500 bones, not counting other resources). Out of 200 games with RP, no one complained, right? Well, that's because it was allowed. At the very least, I would have +10-20 wins on Huge maps where I could simply kill my opponent with 2*7 units with full resource purchases in the city.
For all players, in any case, with RP allowed, the win rate will increase thanks to it; it can't be so insignificant that it can be ignored. The benefits of blue don't outweigh the RP rule, and for that reason alone, it shouldn't be allowed, as it strengthens red.
For the sake of interest, it could be allowed for a couple of seasons, just to ban it permanently after a while. :)
