I think it reinforces the idea that allowing user-supplied style-sheets is
a significant a11y consideration - in other words authors should avoid
inline styles whenever possible in favor of linked styles so that some
users who desire alternative display contrasts (etc.) can do so with
stability/predictability. I believe Wayne Dick (CSU system) has written on
this issue in the past, but I was unable to actually put my hands on
anything quickly.

Agreed, for the most part this will/should remain an end-user
configuration issue. My reverse contrast friend has set her system up so
that the reverse contrast is system wide. However as content authors we
should still be conscious of the fact that finer control can be applied
via user style-sheets, so again avoiding in-line styles has benefits
beyond "ease of editing" considerations.
