If it makes you feel better, SPAs were a mistake when they were all the craze in Flash. Also way before that in Director.

In those two cases, they signified (or accelerated) the end of the useful lifespan of those languages.

SPAs, like frameworks, always make some things easier and some things harder. As long as you stay within the lines of what is easy, you are good. As soon as you stray outside those lines, you get punished.
