Yes, these are examples of ways to explain the process, what it could look like and what challenges are involved during a potential questline addition. They need to be present, it gives substance to the questline itself. Her problem is addressed as critical and cannot be easily fixed after the two upgrades, so it could be parts other than external to the engine and rather internal.
No plug and play option like the first two upgrades. Her questline starting with two fetch quests should end with something more engaging. Her overall story comes off as neglected, adding content to fix her by sticking to the current theme she's been subjected seems like a waste.
