From a development perspective that makes sense. I'm not sure that
many people would have the knowledge to put their own style sheet together
though?

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.
