I'm almost the exact opposite opinion. One of my biggest gripes with web apps, especially on compact laptops and other mobile devices, is the constant presence of screen-space-hungry browser chrome. On Macs this is sometimes compounded by the addition of a redundant, in-app menubar since web apps in browsers (and for now, even PWAs) can't use the macOS global menubar. Back/forward/history can be nice in some circumstances, but to me if I find them needed to make a web app usable, it's an indictment of terrible navigation UI/UX design on the part of the app. It's not that difficult to design an app to not need to lean on browser controls, but it does require a bit of a more holistic approach to UI/UX design than is commonly found in web apps (where instead, everything tends to be diced up into heavily silo'd screens). The other gripe is that these apps are making my tab clutter problems worse than they need to be. With a PWA I can make use of OS window/app management functions to help keep things sorted a bit better and make my tabs almost entirely transient rather than constant presences, easing tab management.
