We need a way to be able to select between separate sets of icons before replacing the current one. Please see #319966: Add flag icon theme selector if you want to help. (Also, there is a Romanian flag in the 6.x-1.0 release.)

Also, if you could provide any information on the usage terms on this icons, that would also speed up the process of adding them, once the above mentioned issued has been resolved.

But if we add them here, we'll publish them under the GPL. Unfortunately, both the GFDL and CC by-nc-sa licenses are incompatible with the GPL. So we can't include this. :(
