Well from experience backend tech stacks are way less mutable.

But let assume you did want to change backend you will take into account your HTML templates and find the right template engine where you might just copy past your templates folder and do some light configuration work.. If that is not possible refactoring the templates parts shouldn't such a big issue.

I see HTMX more as a way to keep far and far away from frontend frameworks, I can focus on being productive with Html, CSS and HTMX and call it a day. With react you need to learn HTML, CSS, moderate amount of javascript/typescript, state management, build tools etc etc.

But you make a good point about React SPA just consuming json or whatever other non html data format.
