If you're aware of it being not an API method, it's okay to override it
-- I just wanted to make it clear that we can't ensure that your
application won't break if you upgrade in that case. In this case, what
would happen is that when you upgrade to 2.5, your behavior would just
revert.

I think you can see now how to override the function, so you can go
ahead with it if need be. Let me know if you have further problems.
