There comes a point in a project where the amount of client-side features requested makes you wish you had started with a fully-fledged modern framework like React. New features could be a single React component plus some updates to existing callbacks, and a new API call, but instead requires adding to a big accreting ball of HTML templates and a hodge-podge of vanilla (and maybe jQuery) js amounting to a bespoke framework that someone had to develop to manage the complexity.
I absolutely love Django and old-style web frameworks, but they are not without their own complexity risks.
