Hmm, a few more tests. it now looks like in case the command line is

./notmuch-emacs-mua --client --auto-daemon

Then the --create-frame should be implied. w/o --client --create-frame
would ... well, create that (only) emacs frame anyways... oh, the
combinations; for reference I just paste from my history...

So. I'm going w/ the suggestion making --auto-daemon imply --create-frame
