I know some of the other defaults in older versions of pqm-submit
caused problems for Launchpad developers (pqm target branch mainly),
which we fixed by getting it to print an error message rather than
pick a default value.

This sounds like a similar case, so will reduce user confusion.
(Unless John can think of a good reason to keep the push location and
parent fallbacks in place).
