I think that’s a pretty good impression. Lots of features for those cases:
- better behaviour under packet loss (you don’t need to read byte n before you can see byte n+1 like in tcp)
- better behaviour under client ip changes (which happen when switching between cellular data and wifi)
- moving various tricks for getting good latency and throughput in the real world into user space (things like pacing, bbr) and not leaving enough unencrypted information in packets for middleware boxes to get too funky
