Actually keeping the RPC metadata as it is found in the sources (with the exception of Pleiades and their weird center of pixel (1,1) convention perhaps, as proposed in https://trac.osgeo.org/gdal/attachment/ticket/5993/fix_PleiadesRPC.patch ?), and doing the adjustment in the computation will be less disruptive for the existing code than modifying the RPC metadata values for a half-pixel shift in all deserializing/serializing .rpb and _rpc.txt code (+ you'd have to make a special case when deserializing/serializing the RPC metadata domain in .aux.xml and VRT !), so on reflection, I'm happy with Pablo's approach.
I think this is also nicer for third party applications that use the GDAL RPC metadata. Changing the LINE_OFF and SAMP_OFF would also require changes in third party code.
