Recent changes just went out this morning, one being the ring/trinkets/necklace can be bought across the account once unlocked so that is a great change also a new change has been done to give 40k bronze to people who did not farm frogs.
Source for more bronze for non-froggers: WoW Remix Adjustments and Improvements Coming Today
I think that while it is a bit messy this is probably a good solution that can be done without overtly nerfing people who spent hours in farming but also provides a way for people to get cosmetics on alts easier while encouraging leveling alts which was one of the appeals of the event.
I still think bronze being the same currency for upgrading gear and cosmetics can feel very limiting but at least the option is there for alts to get cosmetics more easily.
