The jobs will just become (even more) horrible amagamations of fullstack development mixed with customer service. Meaning you'll be forced to sit on "urgent" live support lines and incident bridge calls, management will expect you to magically be able to answer any question about all facets of every integration and table the stupid thing touches, at the drop of a hat, including the vibecode garbage some other team just deployed yesterday, and you'll also have to do tier 1 type of tickets where you walk some illiterate fucktard through how to click the single sign-on button.
