Back in the day, reducing total HTTP requests meant less time waiting through the network lag (round trip times). With HTTP2, that's less important because it allows multiple requests simultaneously on the same connection (fewer network connections made=less lag). It's a nice to have feature and has measurable benefits, but I don't rely on it. There is a non-negligible cost for the browser to parse yet another CSS/JS file, but I'm not sure exactly what those costs are.
