Yes.

| vstring_strncat(state->output_buffer, text, len);

Maybe other MUAs create valid emails with only CRLF when passing
over to the MTA, or simply do not use line continuation when the
email is to be passed to the MTA.
Plus DKIM is maybe not used widely by the my-MUA-is-a-shell-script
folks yet.
