I know it not straightforward, I said easy, not "it's there, just 
activate it". I am aware there would be issue and something would need a 
But I am quite confident it could be done.

dpkg and whatever other app that install application on the device can 
be executed by root, but they can run the 
pre/post/during/you_name_it-install script as 'user'.
If they are not though already like that, I do not welcome patching the 
dpkg itself.

I am not a dpkg guru, but I will take a look at it. Who knows if they

After all it makes sense also on a regular desktop.

That's a different matter. Badly conceived apps can still and will cause 
damage. No matter how are they ran.
