MOC has nothing to do with that. Moc doesn't see your entire codebase, doesn't 
transform it, doesn't remove code. That's a complete misconception of what moc 
is about.

What you're asking for already exists and is called "static build". That 
causes the linker to discard everything that your app doesn't use.

That is also not what Qt Lite is about. Qt Lite is about making changes that 
are not allowed in Qt 5 due to binary compatibility reasons that will cause 
smaller code. It's also about reviving the old feature system so that you can 
depopulate dynamic libraries instead of being forced to use static.
