It's not a question of POSIX telling us what to do. It's a question of
what is a good thing for GNU grep to do, and making sure that this
behavior conforms to POSIX (at least if POSIXLY_CORRECT is set).
When grep encounters binary data, there are different "good" things to
do depending on the application, so grep has options. The behavior
you're asking for is available as an option. As I understand it, the
main point of your bug report is that you want the option to be the
default behavior. However, that would adversely affect some other common
uses of grep and it's not clear that it's a good idea.
