Well, I'd be disturbed by a dd that defaulted to 1G blocks.  I'd be
even more disturbed by a /dev/zero that reached EOF after only 1G.
(I'd also wonder why the time is printed to millisecond resolution but
the transfer rate is rounded off to either an integer or two
significant places, I can't tell which.)

PS.  :-)  Seriously, this looks to me like a suitable approach.  People
who don't like the typing involved for msgfmt=human on interactive use
are invited to create shell aliases, or script in their personal bin
directories.  Perhaps add a msgfmt=tty-human which tests isatty(2).
