Right, so you agree: you have to reimplement it. You can just use a framework to do so.
It might be news to folks to learn that every single SPA framework has solved the problem entirely because it's really not an uncommon experience to have your browser history broken by a SPA. I believe that most frameworks implement the API correctly. I also believe a good number of developers use the framework incorrectly.
Or simply unaware about the whole "back button" debacle. Which is yet another stone to throw at the SPA camp: if using technology A requires a programmer to learn about more stuff (and do more work) than technology B for achieving pretty much the same end results, then technology A is inferior to B (for achieving those particular end results, of course).
No, it’s like saying you’ve been provided with a calculator but may, if you wish, create your own calculator with some parts provided. No guarantee it adds numbers together correctly.
