Of course, non-packaging contributions are very valued and very welcomed.
But it just doesn't sound possible to address them in the same survey,
where the focus is really on welcoming packaging contributions. Even the
initial surveyed group would have to be different, as I plan to survey
people who have recently got their first package accepted in Debian.
Also, this is not the ultimate and final Debian survey on new
contributors. It's an experimental attempt at trying to collect some
useful data, and to do so so we have the data available at DebConf.
There's place for other projects and ways to do that, of course.
For example, the GreenHouse project aims at building infrastructure
to identify, welcome and retain new contributors.
