And then you go on to quote your particular example about ENBD.

Which is where you state what you've stated on this list.

Not really.  It explains why Linux Software RAID isn't good for use over
ENBD but not why it's crap in its intended configuration in one machine
yet you persist in claiming it is without giving any good, hard facts.
It's getting harder to believe this.

So which bits "are not *solely* related to use with ENBD either"?
(Yes, I know it appears I'm being a stubborn bastard on this point -
that's because I *am* a stubborn bastard but I'm also interested in
arguments based on technical merit not rhetoric so show me the facts and
I'll be happy)

I'll admit the documentation (well manpages) leave something to be
desired but the RAID HOWTO is fairly good (or at least was when I first
setup RAID).
