No plans (focus is currently on Tomcat 7 bugs and Tomcat 8) but a patch that implemented ping should be pretty simple and is very likely to be accepted. ping() is almost just a copy and paste of pong(). An enhancement request in BZ is the way to go with this. If you are able to provide a patch in the next few days it will almost certainly make it into 7.0.33 else it should be in 7.0.34.
