I can do that - have the <a> tag with the MY_SITE_NAME block conditioned on the block's existence, otherwise use the global area. It will, however have to break the old fallback of "echo SITE" since it is not compatible with multi-languages.

Another option is to keep the old logic for single language sites and kick in the global area only for multilingual sites where $logoSuffix is the logical equivalent of true.

Your preference?
