All front-end devs should be able to switch to that BFED mode though, especially on pages that don't _need_ to be fancy. This helps with cross-browser compatibility and pagespeed. You could still be fancy, but only as a necessity and even then it should be layered on the BFED-side. The problem with devs nowadays is they skip the BFED and just jump into SPA's without knowing how to make a well-working website without tons and tons of sass/js.
