As far as I know, welcome-exempt is set by staff so that overrules any local settings. Furthermore, the welcome messages are done by bot which does not provide a means for local admins to ignore the welcome-exempt flag. If an admin wanted to have a welcome message on a welcome-exempt user's wall, they would have to create the thread manually.
