BotH is about more than just gold. It's the gear combo's it provides. When running normal rifts, I run my WD pet gold and Monk Sunwuko gold setups, both on T6. Having said that, at 130-180 mil/hr and turning at 30b+, it doesn't hurt to amass such riches, as now you can re-roll a stubborn gear piece until you get what you want (I've had to do 20m per roll before getting what I need on gear, and cared not a bit).
Even without the BotH, you still end up with insane gold.
BotH is useless in GR/Trials anyway, you may need gear upgrade/setup change if you need to the Gold combo to survive T6.
