Correct me if i'm wrong, but what he wants is, that everytime you are going to install an app from extras-devel, the n900 should ask you at least 5 times if you are sure, type a confirmation code, sound an alarm informing you that your phone may (or may not) be damaged if you install, AND, before installing it, require the handwritten signature of at least 5 members of the maemo.org forums, accepting an agreement that you won't create a post on the forums in the case your phone gets damaged (annoying abill_uk) asking how to fix it.

Seriously, these kind of threads are more annoying than the ussual "i hate nokia" "nokia sucks" "n900 sucks" threads around.
