Yes and not everyone likes either Siptah or EL and some play on Savage Wilds or other custom maps without any caravans or events or anything 
Your point being?
Why would there be any obligation on Funcom to develop their maps equally?
And how would it make sense for a story that’s been initiated on the exiled lands… by the set religion trainer who is a sorcerer imprisoned there… to be unfolding on… Siptah?.. The dude himself said that if he could remove his bracelet then none of that would be necessary as he could just magic away 
without all the silly blood crystals and whatnot.
However that’s a bit of a lore-sided explanation… The real one is what Codemage presented in another similar thread:
Even so! Aside from the story though, every other part of the new Chapter, including golems and blood crystals and the journey revamp with Siptah specific entries… it’ll all be there
