You are not alone I wish that the scarf or neck piece could be part of another chest armor section. One potential solution for all these issues could be to replace the toggle Prime details checkbox with a tab that allows you to enable or disable different aspects of the default Prime details, similar to how we can manage attachments. Instead of having these details permanently integrated into the frame, this approach would offer more flexibility. For instance, consider Ivara Prime; why would you want to add extra armor on top of her existing Prime shoulder armor? It can disrupt the immersion, especially when the frame already has a bulky appearance. There always appears to be some inconsistency in Prime designs, which defeats the purpose of using attachments. Trying to add more chest armor on top of Wisp's already bulky scarf just doesn't look right.
