I have no comment about this. In an ideal world, sendemail.perl could
be taught to support --git-completion-helper but I don't think my
little remaining Perl knowledge (or time) is enough to do it. Perhaps
this will do. I don't know.

So "all", "attach", etc. are added to this list while these similar
options are lost from the other variable?  Is this a good trade-off?

Not sure if I understand you correctly, but it looks to me that the
options in git-send-email.perl are well organized, so we could add
--git-completon-helper in that script to print all send-email specific
options, then call "git format-patch --git-completion-helper" to add a
bunch more. The options that are handled by setup_revisions() will
have to be maintained manually here like $__git_format_patch_options
and added on top in both _git_send_email () and _git_format_patch ().

So, nothing option is lost and by the time setup_revisions() supports
-git-completion-helper, we can get rid of the manual shell variable
too. The downside is, lots of work, probably.
