Dragonflight: Alchemy and current Masteries

I’m not sure if it’s been mentioned elsewhere or on other forums (thought I couldn’t see it in a quick search) but does anyone know if the current Alchemy Masteries will be still be in effect in Dragonflight?

Say, for example, one of my Alchemist toons was a Potions Master. Would that Mastery carry over into Dragonlands? If its still active, would it provide any benefits when crafting Dragonflight potions…or Exlirs or whichever other Mastery the character happened to have?

I do not believe it will carry over as they haven’t in the past. Each expansion is separate, right?
