I guess we could go for this if at the same time it is agreed that packages can be pulled from Extras back to Extras-testing if problems arise later on.

That is another problem. Packages were pulled only when there were serious problems floating and after contacting personally the maintainers. The Load applet for instance is still there, even if the bug is evident. Still, the responsibility of pull it off (or even ask for it) is not defined and there you have still the app getting more downloads and confusing more users.

And don't get me wrong, I don't blame the developers! Bugs happen, problems happen. This is not about being harder in order to try to prevent problem, but about being more flexible so the problems can be dealt easily when they come.
