In practice cat is commonly used to handle binary files. Also cat does
not process files in any way. It's pointless to convert input from
external to internal representation just to output the very same data
with the backwards conversion. Cat should use binary mode.

In which way? As far as I see this example should work the same as under
Unix. Other uses of grep might have different behaviour than on Unix.
But in most cases that I can imagine off the top of my head, I don't
have any trouble arguing that grep should not really be used in those
cases in the first place.

That is what binary mounts do. At the expense that tools that deal with
and process text files (like bash) suddenly break, when they get fed
native text, even though the tool is written correctly. IOW binary
mounts favour broken tools instead of correct tools.
