> full functionality can’t be dependent on an app which is only available on Mac OS and/or Windows.
The existence of 1Password X means that full functionality is not _dependent_ on a MacOS/Windows app. The argument that there should be a graphical (because there _is_ a multi-platform CLI), native app for Linux, which does not depend on any browser, is a perfectly valid one -- but it is also an argument that I don't believe they've made.
