Yes, I know, and I didn't mean to say anything else.

But AFAICS, the result of the gnus-alias automatic identity mapping is
limited by what is possible in a message-setup-hook.  That's what I tried
to express.

Sorry if I've misunderstood something, but I really don't understand how
that could work.  Not sure where the authoritative source of gnus-alias
is.  Doesn't look like it is part of emacs.  Google gave me a github
repo, but I don't know if that's correct?

Anyway, that version seems to do automatic identity mapping by adding a
hook to message-setup-hook - which makes sense:

https://github.com/altruizine/gnus-alias/blob/master/gnus-alias.el#L666

I understand that you can insert anything into the message buffer here.
But Gnus has not yet inserted the yanked text, so you cannot position
your inserts relative to that text.  Anything you place at the beginning
of the body will be moved around later.

There's a lot of code spread over many functions, but I believe
gnus-summary-reply() is the best place to start looking at the problem:

https://github.com/emacs-mirror/emacs/blob/master/lisp/gnus/gnus-msg.el#L1061

It ends with:

	(message-reply nil wide)
	(when yank
	  (gnus-inews-yank-articles yank))
	(gnus-summary-handle-replysign)))))


Where message-reply() will call message-setup() as its final step, which
in turn will run all the message-setup-hook hooks.  See

https://github.com/emacs-mirror/emacs/blob/master/lisp/gnus/message.el#L7314
https://github.com/emacs-mirror/emacs/blob/master/lisp/gnus/message.el#L6823

This means that gnus-inews-yank-articles() runs after any automatic
message setup by gnus-posting-styles, gnus-alias or my own personal
setup hook.

gnus-inews-yank-articles() can be configured to insert the quoted text
above or below the message, but I can't see any obvious way to allow it
to insert the text between any existing mml tag and the rest of the
message body.  Which is where I'd like it to end up.

One could also have imagined a solution where it was possible to control
gnus-summary-handle-replysign() by a buffer local variable.  But it
depends on the sign/encrypt status of the message being replied to, using
the variables

 gnus-message-replyencrypt
 gnus-message-replysign

And that is not exactly what I want either.  I want to sign *all*
replies from a specific address, whether the original was sined or not.
