I guess I'm confused.

AFAIU, "add -b" names a branch in the repository _from_which_ we add
(i.e. the upstream), which in this case is elpa.git.  So I don't think
I understand how your previous sentence:

   ada-mode would be kept inside emacs.git in the branch
   `elpa/ada-mode`

can be reconciled with the Git command you show.  What did I miss?

In any case, if elpa/ada-mode is a branch within emacs.git, then how
can we build some branch of Emacs in a way that includes ada-mode, or
produce a tarball from that Emacs branch?  For example, emacs-NN
release branch will be different from the elpa/ada-mode branch, and we
can never have them together unless we merge them in Git, which is
probably not what we want?
