I think there's nothing special about 'guix home' or ExWM here; it
happens with any Emacs package installation; Emacs must be restarted
completely (M-x guix-emacs-autoload-packages doesn't suffice).  It's a
regression that was introduced with the move to use
subdirectories/subdirs files for the Emacs package installation layout,
in 79cfe30f3eb10bd3dbf7aa0f6e873c945d7d0ea5 ("build-system: emacs: Use
subdirectories again."), if memory serves.

We should open a bug about that and see if we can come up with a fix!
