No, I don't agree with it. You are essentially suggesting DLC.
The better solution is not to design an expansion that requires x, y, or z resources and equipment in order to play the new expansion. That's a design decision you can easily make. They shouldn't have to have an Archwing, a Railjack, and a Necromech, or WHATEVER the requirements are (since I don't know) to play "The Man in the Wall" in order to play "The Man in the Wall" or "Warframe:1999."
You didn't need to have played any of Warframe to start "The Duviri Paradox," it would have made more sense, but it wasn't a requirement.
Every new player should have to play the tutorial. Then, if they want to hit the button to play "The Man in the Wall" let them if you take away needing any item to start the quest. Put up an explanation and let the player decide whether to continue while knowing very little about the game's lore or not. Leave it player's choice.
But, if DE wants to go the route of DLC, call it that and not sugarcoat it. And then let your player base decide how they want to respond.
