I've also developed lots of server side generated webapps (edit: websites) and I still like the SPA approach more because it's more clean and domains are better separated. So the answer is usually yes, to me it's worth it if the problem requires SPA.
You make it sound like SPA-s are like the Death star, but this is really far from the truth.
