As a practising JavaScript-decliner for a few years: your “only 5% work” figure is wildly, extremely wrong. It depends a little on what types of sites you’re dealing with, but for contenty sites rather than appy sites, I’d put it past 95%, with a few notable major site exceptions (so that by content it may well be below 95%) and certain subcategories that are more commonly broken.

And I’d say the battle has actually gained some ground in the last eight years, as server-side rendering of JavaScript content stacks has made headway.
