I agree and ( although not yet aimed at the N900 ) to that end I have just added the following to the top of the first post of my announce thread:-

WARNING

Feel free to play with this software, but be aware that this is software under development. Do not install software from either Extras-Devel or Extras-Testing unless you know exactly what you are doing.

Unless you are a developer or an experienced tester you should not have these repositories configured.

Until informed otherwise all software refered to in this thread is suspect and may seriously effect the utility of your device. Although not dangerous to it physically it may seriously affect the utility or battery life of your device in lots of as yet, unknown ways.

It may be worth mandating something like this for all.
