Thus if possible, I would prefer not incorporating functionality from these thorns into IllinoisGRMHD.

Just a quick comment: maybe it would be possible to isolate all such "extra" functionality in a single source file, and make it clear that this is only present for compatibility, and isn't relevant to the internal workings of the thorn.  It is true that compatibility code can make things cluttered, but maybe having it separate would be enough?
