I'm not sure that's all there is to it (Have you tried setting it to
VRAM instead of GTT?). With write-combining, I wouldn't expect CPU
writes to VRAM + blit from VRAM to be significantly slower than CPU
writes to GTT + blit from GTT. I think the problem is rather that
without specifying a domain explicitly, the BO starts out in system RAM,
incurring additional overhead when rendering from it.

So while I'm okay with the code change, I suspect the commit log could
be better.
