There is no reason it shouldn't.
Initially it was done that way only because doing something
unusual should be done under explicit user permission. Binary
patch is not "unusual" anymore, I guess ;-).

[PATCH] Make apply --binary a no-op.
Historically we did not allow binary patch applied without an
explicit permission from the user, and this flag was the way to
do so. This makes the flag a no-op by always allowing binary
patch application.

- When applying a patch, which is a git-enhanced patch
- that was prepared to record the pre- and post-image object

- the object the patch applies to (i.e. "index" line's

- and the post-image object is available in the object
- database, use the post-image object as the patch
