I'm not opposed, but previously Tom explicitly said that he thinks this feature
is useless and is strongly opposed to making any kind of promise that the
current interface to make it possible (if get_query_def() is exposed) would be
maintained. Adding such a test module would probably a reason to reject the
patch altogether. I'm just hoping that this change, which is a no-op for
any legal query, is acceptable. It can only break something if you feed wrong
data to get_query_def(), which would be my problem and not the project's
problem.
