Larian has explicitly stated this was untrue. I don't see any reason to disbelieve them as her entire arc seemed to be leading up to that scene on the docks.
Well, that would mean her entire original arc is: A pair of fetch quests, so she can touch people again -> "Isn't life unfair" -> Death. Meanwhile, you have the Gondian + Steelwatch connection that fizzled out after it being setup at the start of Act 3 and possible datamines for cut Upper City content (Which I personally havn't seen evidence for, but people were reporting it last year)
