This isn't implemented yet.

Well, an easy way would be to add a new property to ClassGroupProperties
instances for the size and to extend the renderer and the GUI
accordingly. To round it off, one would need to extend the file format
to handle the sizes too. It shouldn't take more than a few hours to get
an initial version (depending on the familiarity with Thuban's
internals). Getting it right would take longer, of course.

I'd say it's part of the "Symbols/Fill Patterns" entry for Thuban >1.2.
At least that's where it seems to fit best in the current road map. 

My impression is that the road map beyond 1.0 is very tentative still.
It depends on what the Thuban users need and on the functionality we
need for our projects at Intevation. It may well be that more flexible
classifications will be implemented at an earlier point than the current
road map says.
