Consider that that's a thing in the PDF header.
We should be able to have that thing not to use the same primitives, or
anyway have that follows SDE.

Such a part alone might have a chance to be accepted upstream, as IIUC
their main concern was about changing the actual visible output, but
they should be fine with changing the headers (as they already did in
other parts).
