This development style might be a better DX for the teams. But Facebook on the web is an absolute dumpster fire if you use it in a professional capacity.

You can't trust it to actually save changes you've made, it might just fail without an error message or sometimes it soft-locks until you reload the page. Even on a reliable connection. Error handling in SPAs is just lacking in general, and a big part of that is that they can't automatically fall back to simple browser error pages.

Google seems to be one of the few that do pretty good on that front, but they also seem to be more deliberate for which products they build SPAs.
