I'm not against new features, I have myself introduced a number of new
features from 6.4.0 to 6.4.2. What I wanted to say is that I fully
agree with Helena and Hamish about the need for testing, that we may
need to think about a way to highly encourage testing before
backporting to 6.4, and that testing before submitting changes is IMHO
generally a good idea.

If you say that taking special care about three different branches is
too much for us, that means that changes really need to be tested for
7 as as well before submitting. As I said, in most cases testing can
be quickly done by the person introducing the changes, because that
person should know best what to test for.
