So it is now equivalent to binmode FILEHANDLE, ':raw'? Point accepted, although it was a no-op when I learned Perl in the 5.6 era and seems to remain so absent the special configuration that you mention.

None of my scripts omitting binmode on POSIX have blown up, but I do not have PERLIO set nor do those scripts use open. (Nor will those scripts ever be distributed in their current forms, as I know that they are not portable.)
