At the bottom of the dev1242 post, it states the following -- which led me to think that some items will be completely removed, including from our inventory. Or am I interpreting this wrongly?
Ingredients becoming obsolete
These items will be permanently removed from the game.

Fortunately for the OP, Goobbue skins are listed under this other category of items, so I assume they will remain in our inventory if we choose to keep them:
Ingredients that may return in a future patch
While not currently in use, there is a possibility that these items will find use again in the future due to considerations such as name availability and consistency with lore. At this point in time, however, we cannot guarantee whether and when they will return.
