    We will have to implement them in Gnus if those arguments are
    really required,

Please make them work.  It does not have to be done right now,
though.

                     although I think it doesn't solve the problem
    that `sendmail-user-agent' overrides an existing *mail* buffer.

I am not sure what that means, or whether it is really a problem,
but it is certainly a different issue.  If you want to raise it,
please send a bug report about it.

    IMHO, implementing SWITCH-FUNCTION is regression.  Because, in
    the case that `mail-user-agent' is `gnus-user-agent', we can use
    the `gnus-buffer-configuration' feature to customize how to pop
    to a mail buffer up variously.

Those features are fine, for when the caller has no preference,
but if the caller specifies a particular method, Gnus should
not just ignore it.

      For CONTINUE, it is hard to me
    to imagine the situation where I want to use an existing *mail*
    buffer in order to compose a new mail.

CONTINUE means the user has given a command to resume editing an
existing draft outgoing message.  If the user wants to "compose new
mail", he will pass nil for CONTINUE.


      Anyway, that Gnus users
    set `mail-user-agent' to `gnus-user-agent' is the best, I think.

Since I don't use Message mode or Gnus, I do not know that
message-user-agent differs from gnus-user-agent.

Does gnus-user-agent implement CONTINUE and SWITCH-FUNCTION?  If not,
the same things I said about message-user-agent apply also to
gnus-user-agent.
