As a point of information, it does happen for gawk.
The grep team must decide for itself how important it is to be the source
for code that works correctly in other projects as well. The existence
of the option to supply brackref = NULL indicates that being able to
work correctly in both cases is supposed to be possible (at least
conceptually).
