If there is a need to split, then sure. But I think Damien had a hard
requirement that writes had to be inlined but that reads didn't _need_
to be for his dm-zoned usecase. Damien may not yet have assessed the
performance implications, of not have reads inlined, as much as you
have.

So let's see how Damien's work goes and if he trully doesn't need/want
reads to be inlined then 2 flags can be created.
