Qt models uniquely for mobile or desktop

[Jan Mulder]

I found out (more or less accidentally) that, for example, the 
divelistmodel.h/cpp code is uniquely used in mobile only. It is highly 
likely that this is true for more models, or models that are uniquely 
used in desktop.

So my question (mainly to Dirk, I think). Is it worthwhile to adapt our 
build system to make this more explicit? I would at least help 
developers to realize this. Not sure it would help with respect to 
footprint of the (primarily mobile) application, as the tool chain might 
weed out that unused code.
