I see lots of questions cropping up about Wubi limitations. The thing is already dead and fated to just go away eventually. Should new users see this in the community bulletin block on the landing page?
As long as we have a supported operating system WUBI should be supported, endorsed and advised (but with other options as being better) as a valid method of using Ubuntu.
Even the download page still gives the option to use it http://www.ubuntu.com/download/desktop/windows-installer :
With Wubi, our officially supported Ubuntu installer for Windows, you can install and uninstall Ubuntu easily and safely. For 12.04 LTS only.
Windows installer is not compatible with Windows 8 or UEFI firmware, and is not available for Ubuntu 13.04.
As long as that page exists I disagree on us stating WUBI should not be used anymore. The disclaimer above is more than enough.
Until April 2017 questions about WUBI are on-topic; a statement on the landing page will not stop those questions.
