The more I work in web development, the more I conclude that the majority of web teams are just not skilled/disciplined enough to build an SPA when a static site will do.
Static sites do not have to worry about:
- memory leaks
- the back button / history
- scroll state
- focus state
- page lifecycle (tab freezing/unfreezing)
SPA frameworks should come with a "you must be this tall to ride" sign.
