I've always hated them but it's good to see the tide turning. Slow (one of the first signs of an SPA - a page with its own custom loading indicator), requires JS to do things that otherwise needn't, and things like links don't work right. I do wonder if the otherwise superfluous --- and constantly changing --- JS requirement is part of the "weaponised change" approach of Google to furthering its control over the browser, since it's relatively trivial to create a browser that's usable on sites that need nothing more than HTML forms, but substantially more difficult to create one which will work with the simplest of SPAs.
