After bug 202701 options can be excluded recursively based _IMPLIES in the master port. As you can see -nox11 port doesn't exclude just X11 group of options but also CANNA.
Alas, review D5538 is not enough here. _EXCLUDE hides _IMPLIES=X11 options from BATCH but not from |make config| which is unlike the behavior for regular options.
editors/emacs-nox11 has been merged into the nox flavor of editors/emacs and the X11 option has been removed.
