Yes, Immersion works in WoW Forever: its TOC lists interface 16001 and the release is packaged for Forever. It replaces the quest window with a cinematic view, showing the NPC's model and revealing the text line by line. See its add-on page for the latest status.

Why it suits Forever
Forever adds over a thousand new quests, so it's worth reading them on a first run. Immersion turns quest text into something closer to a conversation, and its keyboard controls let you accept and continue without hunting for buttons.
If you level fast
It adds a little time to every quest, since the text plays out. If you're racing to 60, you can skip through it or leave it off until your second character.
What it doesn't do
Immersion only changes how quests are shown. It won't mark objectives on your map. For that, pair it with Questie or another quest add-on. DialogueUI is the alternative if you'd like a different style.
