I believe so, see second bullet point in:

That is exactly what I am against. Note the words "get rid of".
This prevents parallel data transfer, use of split mirrors and various
other techniques. It sounds neater, but it implies removal of useful
features.
OK, so let's assume that we'll provide an extra facility that doesn't
take anything away but which provides for close to zero config setup for
the simple case. Frankly, that's what the vast majority of people want,
in my experience.
