Yep I see this a lot where people want swappable engineers and no one is able to understand if you have an engineer working in the Frontend most of the time they will not be acquainted with backend work. Nor is there a need or logical way to keep everyone working across the stack to keep them in this swappable state. Each time you change a persons job they need retraining and orientation. Code is code but a drop down menu is not a database insert.
