Yes, saving input won't be possible. But generally, applications that accept user input and cannot save it for some reason ask for confirmation to lose it, so users won't lose it accidentally. Take a text editor for example, you can open it and close it and it won't bother you, but if you write a few words and try to close it, it will ask you whether you are ok losing the data. This is what users expect nowadays. Chrome team somehow doesn't understand/recognize that and instead of fixing the problem in a generally accepted way, tries to rearrange the interface to have fewer accidents, breaking UIs too much in the process and pissing off a lot of users. And that's bad.
