I don't think, I had an issue with this. But, with standard Unix installs, all applications that start with ports less than 1024 must be started as root. Changing ownership just allows wcadmin to see the logs and modify the confs. Another idea is to apply sudo access to wcadmin to start and stop apache with the $APACHE_HOME/bin/apachectl start/stop. Most unix admins would do that because it is just a stop and start. If you clear the logs, and restart apache with sudo, the logs will be owned by sys group/root.
That's my 3 cents, 1 above 2. (:^>
