[2021] This Promo is coming to an end - any word on what will happen to leftover H'oddments?

The last day for this promotion is tomorrow, and there's still been no word on what happens to leftover H'oddments once it's over. Will they be saved for next year? Will they be converted to standard oddments? And if so, what ratio? Hopefully 1/1 since they're actually harder to obtain than regular oddments?

I personally like the idea of these themed currencies for properly themed cosmetics to be brought back, but we need more communication on how these currencies will work. The whole point of oddments was to simplify the different currencies, now these seasonal currencies only make it more complicated and confusing.
