Do we know if every type of stash tab in poe1 will eventually be in poe2?

We're all aware, I'm sure, that the microtransactions are shared between both games. Anything that exists in both, you get in both buying it in either game.

But there are currently things that exist in only the one game.
So we're left with the titular question.
Will all the tabs, and any associated mechanics, in PoE1 eventually have a PoE2 version? Or will some things not be ported?

There are tabs I still don't own in PoE1, that I could buy during one of these stash tab sales, but I only want to on the basis that I'll eventually have that tab in PoE2.
I don't mind picking a supporter pack and clicking on the particular tab in PoE1 store before the PoE2 version is out, so long as I know it will be out.
