I guess another real advantage of SPA is that you get an API for free. Last place I worked, the product people had a genius idea to "build a public API". They decided to give us half a year to do it. We had a SPA using OAuth. I spent a few weeks adding docs, ran Swagger codegen, then declared it finished. Every call our front-ends used was now part of an API. Then we just trimmed out the parts we didn't want to officially support.
