That's not at all what they said. Some of us use browsers that are not chrome. That would mean having to run 2 browser runtimes to get a thin wrapper with chrome.
I believe Firefox has, or used to have the ability to launch a standalone browser without extra chrome for a specific site (maybe not via the UI)... IIRC IE on Windows 7+ offers the same functionality.
If you're using Opera or Safari, I have no idea.
