No I didn't manage to play with ORB much since I'm not much of a Base
user and ORB crashes left and right even when I tried to do some basic
stuff of making a simple report with default everything.

Plus, I briefly looked into the ORB code and didn't find *any* code that
may handle chart rendering or chart data exporting of sort (based solely
on some basic grepping for 'Chart').  It seems that it just simply
re-routes all the charting requests to the default chart2 code.  So,
when ORB itself doesn't add any new chart functionality, why act like a
provider?  That was the rationale behind this patch.

Anyway, maybe I'm wrong and maybe ORB does provide some extra charting
functionality.  Like I said, I didn't really look deeper into the code.

Heh.  I'm absolutely fine with that. ;-)
