I have a feeling this is more to do with developers being lazy than a problem with SPAs.

I wrote my own SaaS product a few years ago as a SPA, using php backend and basically jQuery front end. It runs on a namecheap shared hosting server for $5 a month. It loads faster than 95% of the internet because as I was learning from YouTube and stack overflow, my #1 goal was to be fast. So it was.
