Those don't affect coin or supply productions of GBs, so no. At least not for their coin and supply boosts. They still give goods, so that fall into 'Is it worth the trouble?' I don't think it would be at that point, you would have the arc and dynamic tower giving goods, and you could just build goods buildings with all the population you aren't spending on supplies production.Not st marks for the % coin boost? Or RAH for the % supply boost?
??? Do you have a Chateau? Maybe things are different in beta, where I have mine, but several of your points are wrong. The boost applies to coins, supplies, goods, medal and diamonds. NOT fp packs(always 5fp). In beta I'm in HMA and there are 11 recurring quests and it's possible to abort any or all of them constantly to get to the one you want. On beta, I've just done; 'collect 2 saltpeter' x6; 'spend 8000 coins and 8000 supplies' x6 and 'spend 38fp' x4 all in about 10 minutes. If I was that inclined I could abort all quests to get to the 'spend coins and supplies' one and do it until I can't be bothered to click anymore. So, as I said in a previous post, if you wanted a near endless supply of fp, Chateau's recurring quests could get you it.If you sit in an age long enough and do all its side quests, or abort them, you start getting recurring quests, which can't really be completed fast enough to make viking's thought on it accurate. You may get a 5 FP pack(with a 100% boost from Chateau De Frontenac gives 10) but you won't be able to complete the three recurring quests more than once a day each, so at best, you get 30 extra FP...which isn't bad, but won't make you a competitor against people who have a hundred SoKs among other things.
