Aether current progress also isn't in the client until you open the window, but it opens after and updates as you get more currents. Shared fates doesn't update as you complete fates, you have to close and reopen it.

And, as far as I'm concerned, that's all fine, I just don't want a currency I want to frequently check in there.
Absolutely, I think once it's cached, there's no reason why it can't remain updated. It's not the only currency that behaves this way though. But it does beg the question on why you can see your gemstones at a trader NPC instantly? It must mean that it's already been cached and it keeps track on how much you have. So surely they can easily add it to the menu if they wanted.
