A more true answer would be, most people just don't need every possible feature installed and all of the above reasons are benefits.
That is a good point too, the default features enabled to be the most used ones
but this argument needs to be balanced with the risks the system would be exposed by default.
I am tring to answer this question to clarify :
What would I chose ?
1) a system which uses the most common settings
2) a system that is safe
I think there shall be a balance between them, that is way I find your comment a good point.
Thanks for spotting this,
