They are not removing romance options from custom characters lol. Swen literally talked about how even the Dark Urge could have a romance and get married..
Doesn't Larian classify The Durge as an Origin character, not a custom character though? So it would specifically fall into the "A played Origin can romance an NPC Origin" category.
I'm not necessarily claiming that custom character romance will be removed from the game, just noting that The Durge isn't evidence for it remaining.
