I'm the exact opposite. At least Withers has a story element surrounding his presence. You awaken a mysterious skeleton from a long abandoned crypt. He haunts your camp, occasionally speaking about eerily about fate. For some reason, he is bound in service to you.
As opposed to: here are some scrolls. They only work on party members and nobody else. Don't try to use one on Arabella. Won't work. Just cause.

I like Withers as an idea as well. I really like how resurrections work in BG3 (it has some lore reason in the sense the PCs are special). Mechanically speaking, I am quite happy you can resurrect your fallen main character in camp and that does not lead a reload. That was one of the most nerve wracking things in the original BG1 and BG2: you win the fight but because your main falls at the last moment, you have to reload. I had to play my squishy main PC as a coward most of the time.
Back on topic: Omeluum (?) does hint that even death can not extract it. Halsin says that it can not be removed mechanically. There is a very dark magic in play. It is a stretch but it makes sense and I would not call it a bad writing. It is certainly a good starting point for the whole plot.
