One distinct trend is a belief that a JavaScript framework and Single-Page Architecture (SPA) is a must for PWA development. It simulates a link with a 400ms RTT and 400-600Kbps of throughput (plus latency variability and simulated packet loss). Our baseline, then, should probably trade lower throughput/higher-latency for packet loss.
