In my experience, this isn't really true. Google still can't crawl most non-trivial javascript-powered apps, and if it doesn't work, there's little insight on what you need to tweak to get it working. It hasn't been able to crawl our javascript-powered parts of the site across two major architectures without prerender, and I know a lot of other companies with the same issue.
