can webclient add an option to logon anonymously?

When using webclient you must provide a user name to login, can webclient add an option to logon anonymously? Is there a security reason not doing that?

Create an anonymous user first, then you can logon to the Web Client with username "anonoumous" and no password.

Yes I know I can do this, I can even create a shorter username without password. But still I need to type that username in the input box. If I use a FTP client software, however, I can logon with "anonymous" option directly.
The difference between typing some letters and a simple click might seems small, but the latter one is obviously more convient to user.

You want to logon to the web client directly? just need a simple URL, like this:
http://YourIP/loginok.html?username=anonymous
