Even the older breed of chrome apps had annoying flaws, IMO, when I was playing around with their APIs to get a feel for them about 6 months ago.
I was mostly surprised how it felt that in many ways you were actually more restricted than you were with just a normal web app. Also the documentation was trash and confusing in a lot of ways because even prior to these changes they had made a lot of other changes via deprecating APIs and their documentation was poorly managed to the point where it was really difficult to determine which APIs were deprecated or not without trying to use them in the latest Chrome and having them fail on you. Also, there wasn't a clear roadmap as to what APIs you could expect to be pretty stable and what ones they might suddenly deprecate, breaking your app.
Hearing that the "new breed" has some of these same flaws and some new ones makes me very disinclined to bother checking in with the current technology.
