I don't think that the grammar would become more complex.
For instance, in the POSIX grammar, I suppose that it suffices
to change
and_or : pipeline
| and_or AND_IF linebreak pipeline
| and_or OR_IF linebreak pipeline
;
to
and_or : pipeline
| AND_IF linebreak pipeline
| OR_IF linebreak pipeline
| and_or AND_IF linebreak pipeline
| and_or OR_IF linebreak pipeline
;
