Something like that should be possible. But in reality it's not as easy
as it perhaps seems to be. Some random thoughts:
- Nautilus would need to check every folder whether it is empty or not,
so this could be a speed issue if there are many folders and over a slow
network.
- Nautilus would need to monitor all folders currently displayed in the
tree view for changes, as a change could lead to a change of the arrow
(show or hide). I don't know whether monitoring that many folders could
have an impact. I assume, it is ok with event-based monitoring
(fam-dnotify) but it could be problematic with polling.

The best would probably be to write a test implementation and look for
speed issues.

IMO the icon size and the text size don't correlate that bad (it's the
same as in the list view). The icons would be too tiny if their height
had to be exactly the same as the text size (==> one couldn't recognize
emblems anymore).
