The consumable vendor on Blackrock

The consumable vendor on Blackrock has had some items removed.
Was this an intended change and if so reasoning?
Can't seem to find anything in the devlogs or changelogs that hint at this change.
Are we going to be able to self craft the items that have been taken out?
Are we not going to have access to said items any longer on Blackrock?

Some items no longer in the vendor; Noggenfogger Elixir, Savory Deviate Delight, Swiftness Potion, Both Stealth detection consumables, Living action Potion, Frostweave Nets, drums and scrolls for class based raid buffs.
