Http/2 makes this less important. Perhaps still worth it for CSS, but higher effort things like image spriting might not be as attractive now.

Yes -- in fact some webperf techniques are HTTP/1.1 - specific, and are actually _anti-patterns_ in HTTP/2. Spriting is one such example.
Domain sharding is another.
AFAIK SVG sprites (or inline SVG) are still required to style SVG images with external CSS.
