It adds optional infrastructure at the back end.

Infrastructure has direct and indirect costs, must be built maintained scaled monitored paid for etc etc.

You need a very very good reason to choose to implement optional back end infrastructure.

None of these reasons would be strong enough to convince me to start building and maintaining and paying for that infrastructure.

Are you implying that you would not need a back-end service without server side rendering?
