That's a bug: the 'format' file needs to stay (with value "12\n") so that 1.6 clients recognize the working copy as a working copy. There also exists third-party code[1] which relies on the existence of .svn/format to identify working copies efficiently. Haven't looked yet into a fix. Daniel [1] specifically, the zsh plugin vcs_info - which can be used eg to show wc information in the prompt when cd'd into a wc.
