This _is_ for average joe. It is supposed to render sites where Konqueror is 
being misidentified. If it depends on UA being set to NS4 it will do any 
good. Many of these websites will already work if you set UA to MSIE (which 
is why they have never been updated). 

Layers are hidding for two reasons: 
1. Very few layer features are fully functional (for good reasons)
2. Many websites identify NS4 by using "if (document.layers)".

This means that if a website correctly asks if we support layers we decline, 
but if they just starts using them, it will mostly work. 

Personally I would like to hide document.all the same way by default. So that 
if we emulate MSIE it is not hidding, if we emulate mozilla it is not there 
at all, but when we are ourself, we hide it and pretend it is not there, but 
respond if it's used rather than tested.
