I think a lot of the reason golds will always be better for terran is because the mule can still mine over the scvs mining the gold base so they still mine it out quicker and get more minerals per minute than other races, also because terran is pretty reliant on minerals and gas isnt as much of an issue unless theyre going mech the more minerals they have the better, where as for zerg or protoss its not highly uncommon to see 1 or 2k minerals banked but have gas as their limiting factor, but I spose atleast they changed it somewhat
Not at all. Terran gets mules because protoss gets to chronoboost probes and zerg gets inject so they can both outproduce Terran in workers. So if mules mine the same amount regardless of where you drop them, it's actually disadvantageous for Terran to drop them on gold precisely because you are mining it out faster without the faster income the gold -should- be providing.
