Let me correct you. The "thin" mode in Umbra has been disabled due to upgrade to PoSv3 ... It was not a priority and thus will be redesigned inline with PoSv3 in the coming months.
I have followed this discussion and wanted to add that one of your own @kewde stated when I spoke to him about the code, that the 'thin' mode in SDC was broken:

I know you are the 'source' but your people @kewde used the word 'broken' and not 'disabled'. Come off your high horse and admit that you do not know everything. SPEC has done what nobody else has done and cloned your code and they are about to make it better and you are just pissed off...
