"what has the face `message-separator' *really*
done for us?"
Well, it seems to only be of effect when
`mail-header-separator' has its default
value "--text follows this line--".
I checked, and
- when it's the default separator, I can
confirm that changing the face
`message-separator' does change the
separator's color.
- when I changed `mail-header-separator' to
"---" (or anything different from the
default), the face `message-separator'
doesn't apply to it anymore!
So it's a bug.

The value of `mail-header-separator' gets added to
`message-font-lock-keywords', which does the actual fontification. Using
setq to change the value of `mail-header-separator' did not change the
font lock keyword, despite setting the variable before message.el is
loaded (or is it pre-loaded?). Using the customize interface to set
`mail-header-separator' *does* work as expected.
Dunno if it's supposed to work this way or not.

All the other message faces don't behave like
that but can be set as expected.
Also the wierd behavior that it works with the
default value for the `mail-header-separator'
but not if one changes it.

The issue doesn't lie with the message-separator face, but with how
message-font-lock-keywords registers which text should be fontified with
that face.
Currently, message-font-lock-keywords registers only whatever non-empty
value mail-header-separator had at the time message.el was loaded.

Well, I don't have any under-the-hood
understanding of this problem, but at least
from above the hood, it sure looks like a bug
all days of the week :)
Glad you made an effort to figure it out :)

Right. So I don't think there's a bug here.

Then why do all the other Message mode faces
work as expected, but this doesn't?
And why does it work to change the face when
`mail-header-separator' is at its original
"--text follows this line--", but not when
changed to "---" or any other value for
that matter?
If it isn't a bug, perhaps we should have a new
list/newsgroup called
gmane.emacs.wierd-behavior where we can report
this kind of things in good order?

Actually, I think message-font-lock-keywords can do better:

This is similar to what mail-font-lock-keywords does in
lisp/mail/sendmail.el, namely adapt the font lock keywords to changes in
mail-header-separator.
WDYT?

For reasons explained elsewhere in this thread, I think the current
behaviour is a shortcoming, even if it's not considered a bug. I would
like to push my patch which addresses this, and which I reattach for
convenience. WDYT?
Thanks,

I think that looks like a good solution... did you apply it to the
Emacs repo?

Thanks, I just pushed it to master[1] and am therefore closing this

0. emacs -Q
1. (setq mail-header-separator "--") C-j
2. C-x m
Note that setting mail-header-separator before loading message.el works
as expected.
3. M-x customize-variable RET mail-header-separator RET
4. Change value from "--" to "--foo--"
5. C-c C-c
6. C-x m
Note that "--foo--" gets inserted, but message-font-lock-keywords still
holds the value that mail-header-separator had at the time message.el
was loaded.
Since mail-header-separator lacks a custom setter, it makes no
difference whether you use setq or Customize, so long as its value is
changed before message.el is loaded. Otherwise, you have to reevaluate
and reapply message-font-lock-keywords.

I didn't try with emacs -Q, probably something in my setup ends up
loading message.el at startup.
Thanks,
