For the record, the topic starter and first 2 replies were from [C]ouncil members. It's understandable that they would want this but it should be noted that they're not coming from a neutral perspective.

So you can go ahead and make this change, but I wouldn't expect a noticeable bump in Gallic activity. Why would this change suddenly sprout a Gallic boom when other changes did not?
What will the Council be doing once this change comes into effect? They probably won't be sending trade ships down to Omega-7 to pick up the ore. The likely outcome I forsee is Council snubs camping the 2 choke point entrances to Gallia or to Champagne to tax the Copper ore haulers.
So I think the effect of this on Gallia activity will be negligible and I am against this change because it will likely come with a nerf for the Planet Houston copper ore sale price. The copper ore price at Houston has been good for mining activity in Omega-7. (Disclosure: I do some of my mining in Omega-7).
