Deleting is quite a problem as you don't want to lose settings just 
because you deactivated the plugin. What I did is to use 
plugin_name_setting and delete all plugin_name_ settings if uninstall is 
set up. Therefore there should be some thing be done on how plugins are 
managed. Other systems (e.g. Typo3) make a difference between installing 
and activating. I think it should be done. There still should be the 
activation/deactivation hooks in case your messing around and something 
will break if you get deactivated. But especially having a uninstall 
hook would save you us plugin-developer a lot of trouble. And being able 
to output errors on those hooks.
