Hey.

Is this still being considered?


Yes it still does make sense,
especially as sha1 becomes less popular over time,
in which case the extra processing would matter less.

Hey.

Since on UNIX/Linux it is effectively always binary mode, shouldn't the
(sha|md5)*sum tools default to that, and especially also generate
output with the "*" flag set?


Well they do default to binary mode,
but don't use an explicit flag on UNIX systems
(unless -b is specified).

For compatibility reasons we can't really change thing now,
but note the newer `cksum -a ...` interface which uses
a different format without binary tag.
