Does minifying and concatenating JS/CSS files, and using sprites for images still provide performance benefits when using HTTP/2?

Question

With the new HTTP/2 protocol the overhead created by repeated HTTP requests to the same server has been greatly reduced.

With this in mind, are there still any significa

Answer 1

So far, all the answers tacitly assume that you'll want to download ALL the .CSS and .JS files for every page. A benefit from using http/2 and keeping .CSS and .JS files separate is that you can only bring down the ones you need, and not downloading something is always faster than efficiently downloading it.
