Correct me if I'm wrong, but it seems to me that udev provided the
persistent naming of block devices and also provides a method to fix
this, and the
requirement to adjust one's raid setup was unfamiliarity with this
(new) feature.

I don't know any details. I can just say it was being discussed on
LKML and I don't recall the answer being "use udev". If someone knows
if it has been addressed I would be interested in a url to read about
it.
