It’s usually crappy though, like the URL and the history don’t accurate recreate the state of the app on refresh at all, or the history gets so clogged with every mutation of app state that the back button is effectively useless.
Yes, I know in some theoretical scenario where the developers do everything exactly right none of these problems would exist. My argument is not that it's intrinsic to the technology, my argument is that my _experience_ is that the vast majority of (needless) SPAs are like this. Whether it's because frontend developers get all hot to re-implement standard browser features themself using redux, because the tooling is bad, or what, I can't tell you.
